Add systemd drop-in to wait for snapd seeding completion before starting the
display manager. This improves the user experience as users now wait in
Plymouth for the installer to finish being seeded, instead of in GDM with only
the wallpaper visible. When GDM starts, the installer launches with minimal
delay.
When developping and using snapd from edge on cross-team efforts like
TPM/FDE, allow snapd to reexec to the snap version unconditionnaly,
on live system.
.
This is commented so that the future revert to stable include it and
we don’t forget to readd that next time this kind of effort is needed.
We cannot use After=snapd.service as user services cannot synchronize
with system services. Using `snap system wait seed.loaded` should work,
except for the fact that it requires polkit authentication to perform
this operation.

When the files we're creating in the live layer have static content, ship
them in live-build/ubuntu/includes.chroot.minimal.standard.live instead of
generating them from live-build/ubuntu/hooks/020-ubuntu-live.chroot_early.
Also fixes the fact that
live-build/ubuntu/hooks/020-ubuntu-live.chroot_early was incorrectly writing
to /root in the previous upload instead of /usr.
