configure: Allow systemd service installation without systemd.pc

If the systemdsystemunitdir got passed anyway as a variable, we don't
need the systemd.pc dependency anymore and allow building without a
systemd build-dependency.

Relevant in Alpine Linux, where we allowed systemd services to be
(sub-)packaged (e.g. for downstreams like postmarketOS), but don't have
systemd pacakged in Alpine itself, yet.
