Description: Fixes lintian warning systemd-service-file-shutdown-problems.
 https://lintian.debian.org/reports/tags/systemd-service-file-shutdown-problems.html
 Details:
 .
 DefaultDependencies=no and Conflicts=shutdown.target directives without
 Before=shutdown.target can lead to problems during shutdown because the
 service may linger until the very end of shutdown sequence as nothing
 requests to stop it before (due to DefaultDependencies=no).
 .
 There is race condition between stopping units and systemd getting a
 request to exit the main loop, so it may proceed with shutdown before
 all pending stop jobs have been processed.
 .
 Refer to https://github.com/systemd/systemd/issues/11821 for details.
