dracut: fix running with pre-v103 Dracut

Dracut v103+ moved SystemD cryptsetup code into a separate module, so detect it and when found, use it. Clevis units do not depend on `cryptsetup.target`, so do not install it. The target `cryptsetup.target` is installed by both [90systemd-cryptsetup][1] in v103+ and [10systemd-cryptsetup][2] in v105+, so there is no need to install it by Clevis.
