systemd: install all dracut units in /etc and let the generator cp to /run 

All custom units, which should appear in the system later on should be
installed in /etc/systemd. They should have a guard like:
ConditionPathExists=/etc/initrd-release

So, we can later query via systemctl:

$ systemctl status dracut-initqueue.service
