PAC: Make PAC responder socket-activatable
As part of the effort of making all responder socket-activatable, let's
make PAC responder ready for this by providing its systemd's units.
In case the administrators want to use PAC responder taking advantage
of socket-activation they will need to enable sssd-pac.socket and after
a restart of the sssd service, the PAC socket will be ready waiting for
any activity in order to start the PAC responder. Also, the PAC
responder must be removed from the services line on sssd.conf.
The PAC responder service is binded to the SSSD service, which means
that the responder will be restarted in case SSSD is restarted and
shutdown in case SSSD is shutdown/crashes.
