functions: allow user to pass kern_major_min to snap_validate_seed

Some images do not have a vmlinuz image but a Unified Kernel Image
(UKI). snap_validate_seed do not work for those. Allowing the user to
pass the kernel version of their choice makes the function more flexible.

functions(umount_partition): wait if device is busy (LP: #2030771)

This is a workaround for a series of issues we had recently when the
e2fsck call would fail with the following error:

+ e2fsck -y -E discard /dev/mapper/loop3p1
e2fsck 1.45.5 (07-Jan-2020)
/dev/mapper/loop3p1 is in use.
e2fsck: Cannot continue, aborting.

While debugging this issue, we realized that:
 1. the device was not mounted anymore at that point
 2. no apparent process inside the LXD container is using this device

Thus, it is possible that something outside of the LXD container is
keeping this device busy.
In the past, we tried adding delay (hence "sleep 30") to avoid this
issue. But the device is sometimes still busy even after 30s. Here we
implement a slightly more advanced workaround by checking the block
device status before continuing.

os.open('$device', os.O_RDONLY | os.O_EXCL)

This is the exact same call as e2fsck is doing to find out if the device
is busy or not.
The map page says:

> In general, the behavior of O_EXCL is undefined if it is used without
> O_CREAT. There is one exception: on Linux 2.6 and later, O_EXCL can be
> used without O_CREAT if pathname refers to a block device. If the block
> device is in use by the system (e.g., mounted), open() fails with the
> error EBUSY.

ubuntu-cpc: fix images for hardware devices

Canonical Public Cloud's project seems a bad place to build images for
hardware devices however this is how things were done a we now need to
maintain this.
The recent change to mount the ESP on /boot breaks those images, instead
of adding more hacky things in the hook, create a dedicated target for
those images and use a different hook to build UEFI images.

ubuntu-cpc: disable kernel and initramfs symlinks in /boot

This is required by the new UEFI binary hook as we mount the ESP on
/boot and the ESP filesystem doesn't support symlinks.
We keep symlinks for s390x images which do not use UEFI anyway.

WSL: create a new project "ubuntu-wsl"

For now live-build/ubuntu-wsl is simply a symlink to
live-build/ubuntu-cpc. The only difference is the seed that we use. For
ubuntu-wsl we use the wsl seed instead of the server seed.

Decouple WSL from ubuntu-cpc

Author: Mathieu Trudel-Lapierre
Author Date: 2018-05-28 14:39:06 UTC

Don't divert grub-probe; otherwise we're missing the filesystem UUIDs that
the grub search command needs to find the right prefix/root. This is
different than the PARTUUID for booting initrd-less.

999-cpc-fixes: enable more code on grub2 armhf & arm64

armhf & arm64 images use grub. And despite disk-image &
disk-image-uefi installing all the grubs, some of the configuration is
done in the 999-cpc-fixes. Specifically removal of "quiet splash" is
done there, but not active on armhf & arm64. This results in arm
images to boot with "quiet splash".

Enable running the later portions of 999-cpc-fixes on armhf & arm64.

Drop duplicate call to update-grub, as update-grub2 is simply a
symlink to update-grub.

Add a guard around the call to reconfigure grub-pc, to only do that
when it is installed.

This makes armhf & arm64 uefi images consistent with amd64 uefi
images.

buildd: Fix bootable images

buildd build was trying to use grub's parameter GRUB_FORCE_PARTUUID.
However, this option is not present in Xenial's grub.

To fix this issue, we now use replace_grub_root_with_label to set the
right kernel cmdline parameter for the root filesystem.
