[libvirt PATCH 1/6] rpm: macroize logic for restarting daemons post-transaction

[Daniel P. Berrangé <berrange@xxxxxxxxxx>]

The patterns for restarting daemons post-transaction has a bit of
duplication across the different part of the spec. This is going to
get much worse with the need to restart modular daemons, so benefits
from macroization.
