systemd: do not output status messages once gettys are running

Make Type=idle communication bidirectional: when bootup is finished,
the manager, as before, signals idling Type=idle jobs to continue.
However, if the boot takes too long, idling jobs signal the manager
that they have had enough, wait a tiny bit more, and continue, taking
ownership of the console. The manager, when signalled that Type=idle
jobs are done, makes a note and will not write to the console anymore.

This is a cosmetic issue, but quite noticable, so let's just fix it.

Based on Harald Hoyer's patch.
