fix: ensure we reload systemd during RPM upgrades.

* When we upgrade packages we still drop the latest systemd unit files
  for quads-{db,web,server} and even if they don't change they are
  technically new files.  When they do change we need to tell systemd
  about it.
* When we install QUADS for the first time it's still good practice to
  tell systemd about new unit files, too.
