Fabian Homborg 8c9b4d9000 completions/systemctl: Remove annoying marker
The output of

systemctl list-units

seems to include a marker of '●' or '*' for some units, even if the
output is not going to a terminal and "--no-legend" and "--no-pager"
are given. This appears
to be a recent development, and there does not appear to be a flag to
disable it.

So we simply filter it out in the completions to once again hopefully
offer the actual units.

Fixes #6740
