* systemd - do not overwrite unit name when searching
PR #72702 introduced a bug that changed the unit name when splitting it up for the purpose
of searching for the unit. This only happens on unit file templates on systems that have a 5.8
or newer kernel and a version of systemd that does not contain a bugfix that causes systmed
to fail to parse dbus.
* Use facts rather than a manual probe to determine if systmed is present
* Remov unnecessary block
* Use vars files instead of set_fact
* Add tests for using a templated unit file
* Update changelog fragment
* Use template to get correct path to sleep binary
