Merge ~racb/git-ubuntu:core24 into git-ubuntu:main

[Robie Basak]

This is likely to fail CI, since I think CI is hardcoded to Focal-ness. I tested this locally using a fresh Noble VM using the same hooks that CI uses. Before landing, I intend to switch CI over from Focal to Noble, but that of course will cause CI for anything prior to this branch merged to fail. So I'll wait to do this until just before merging. Please review first!

It doesn't seem worth parameterising this in CI for an event that occurs not more than once every two years (four in this case).

snap: sort stage-packages

This list has an arbitrary order, so sort it to make it easier to see
changes over time.

snap: switch to dash wherever possible

I keep bumping into issues with the user's bash configuration colliding
with the classic snap, due to configuration which depends on things not
present within the snap environment.

It's easier to use dash instead, so switch everything that doesn't
specifically need bash to use /usr/bin/sh as supplied by the dash
package, and stage that package to make it available within the snap.

The one thing that actually needs bash is the self-test. Here, use
`--noprofile --norc` and `unset command_not_found_handle` to detach
ourselves as much as possible from the user's bash configuration.

snap: explicitly enable patchelf

Since override-prime doesn't work with enable-patchelf[1], fall back to
override-stage instead. This works just as well for what we need, except
that it's one step further away when developing and debugging the snap.

This means that the awk symlink is best created in a separate part, so
that we can prime the symlink without messing with the prime file list
generated by stage-packages.

snap: snapcraftctl -> craftctl

Switch from `snapcraftctl prime` to `craftctl default` as recommended by
snapcraft.

self-test: disable pip check

The pip check was useful, but is broken on Noble due to LP: #2084358, so
make it informative only and not fail the entire self-test due to this
failure.

self-test: provide overall summary result

Display a clear overall result at the end of the self-test.

If an early test fails, then we already continue to run to get a full
set of results, which is helpful during development. But this can mean
that the overall result is hidden in the exit status only, and could be
confusing.

snap: explicitly make bin/bash executable

During the build, bin/bash is left without an executable bit and is
distinct from usr/bin/bash. Shebangs that use /bin/bash then fail.

This is a workaround for
https://github.com/canonical/snapcraft/issues/5114

snap: don't install build deps with recommends

Otherwise we pull in pbuilder which in 24.04 starts asking about apt
mirrors. Every dependency should be explicitly declared and we shouldn't
need any recommends for this build.

This script depends on fakeroot, which wasn't being explicitly
installed, but being brought in by the recommends path when installing
git-ubuntu build dependencies. Instead, specify it explicitly as a
dependency of this script. It's really a dependency of the build
environment, and not really a build dependency of git-ubuntu itself, so
it's correct to place it in the former set.

snap: run snapcraft with sudo

It seems that snapcraft doesn't work unless we do this. This is a
workaround for https://github.com/canonical/snapcraft/issues/5113
