pac responder: limit access by checking UIDs
A check for allowed UIDs is added in the common responder code directly after accept(). If the platform does not support reading the UID of the peer but allowed UIDs are configured, access is denied. Currently only the PAC responder sets the allowed UIDs for a socket. The default is that only root is allowed to access the socket of the PAC responder. Fixes: https://fedorahosted.org/sssd/ticket/1382
