systemd: Remove base_libdir if installed only for systemd_unitdir
If a recipe installs systemd_unitdir and it is a non-systemd build than
systemd.bbclass deletes systemd_unitdir (/lib/systemd/) but not
base_libdir (/lib). In this case if base_libdir is empty than following
QA Issue is reported.
ERROR: QA Issue: openssh: Files/directories were installed but not shipped
/lib
If base_libdir was installed due to systemd_unitdir installation than for
non-systemd build it should also be removed.
