reboot-util: unify reboot with parameter in a single implementation

So far, we had two implementations of reboot-with-parameter doing pretty
much the same. Let's unify that in a generic implementation used by
both.

This is particulary nice as it unifies all /run/systemd/reboot-param
handling in a single .c file.
