systemd: add Before=shutdown.target when Conflicts=shutdown.target is used (#546)

Lintian spotted the following issue:

  The specified systemd .service file contains both DefaultDependencies=no
  and Conflicts=shutdown.target directives without Before=shutdown.target.

  This 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.

  Please add Before=shutdown.target.
