configdrive: support upper or lower case labels.

The label on a config drive may end up being 'config-2' or 'CONFIG-2'.
The bug explains well why that is.

This isn't ideal as we end up using blkid twice, but it is the simplist
fix for the moment.

Enable build on Ubuntu 16.04.3 LTS

This patch enables building CirrOS on top of Ubuntu 16.04.3 LTS.

The build failed on Xenial because GCC 5.x changed the preprocessor
output, which ncurses build scripts relied on. This has been reported and
fixed in ncurses and buildroot:

  https://trac.sagemath.org/ticket/18301
  https://git.busybox.net/buildroot/commit/?id=4297e7298edbef6dde75d8bf468441c6a242da5c

However, the fix applied on buildroot does not match the version string
`5.4.0`, returned by `gcc -dumpversion` on Xenial. With this change, the
gcc version `5.4.0` is matched and ncurses preprocessor flags are set
properly.

It was necessary to add python package to bin/system-setup because python
is not installed by default on Xenial.

src/etc/modules: config_drive cdrom support.

config_drive can present as a SCSI CDROM, so we need suitable modules
loaded to access it.

Added in a new section for block storage.

There is no growth in size on Ubuntu, because all 3 modules are
compiled-in already, but the module loading is useful for other kernels
where they might be modular.

src/etc/modules: networking tweak.

- add section
- add lots of commented out modules based on bugs filed in LP, do not
  want the size bloat yet.

src/etc/modules: add nls_utf8, nls_ascii

Improve VFAT support by adding two more very common encodings it can
use: UTF-8 and ASCII.

nls_ascii is frequently compiled into kernels, thus this fix is only
applicable to very modular kernels.
