Bug description:
[SRU Justification]
A package manager bug can cause dist-upgrades from 17.10 to 18.04 to fail because of trying to process triggers out of order. Since the trigger being run is that of the currently-installed plymouth package, it is not guaranteed to be sufficient to fix the version of the package in 18.04.
[Test case]
1. Install plymouth-themes-ubuntu-text from -proposed.
2. Run a release upgrade with each of update-manager -d, do-release-upgrade -d, and apt-get dist-upgrade (the last after manually changing sources.list).
3. Verify that in each case, the upgrade completes successfully, with no errors about out-of-order trigger configuration.
[Regression potential]
noawait triggers have been supported in dpkg since 1.16.1, which is older than the version in precise (https://manpages.debian.org/jessie/dpkg-dev/deb-triggers.5.en.html). A noawait trigger is considered appropriate whenever the triggered package does not need to block the triggering package. There is no reason for a plymouth theme package to need to block configuration of an essential package in this case. noawait triggers are well-exercised in the distro now, so the risk of regression from this change should be low.
There is unfortunately not a known reproducer for the original bug, so
the test case, while it should guard against regressions, is not
strong confirmation that the bug is fixed.
