rpm: macroize logic for enabling/disabling daemons post/postun-install
rpm: macroize logic for enabling/disabling daemons post/postun-install

The patterns for enabling/disabling daemons post/postun-install has a
bit of duplication across the different part of the spec, due to the
number of socket units involved. This is going to get much worse with
the need to enable/disalbe modular daemons, so benefits from macroization.
