Allow krad UDP/TCP localhost connection with FIPS
    
    libkrad allows to establish connections only to UNIX socket in FIPS
    mode, because MD5 digest is not considered safe enough to be used for
    network communication. However, FreeRadius requires connection on TCP or
    UDP ports.
    
    This commit allows TCP or UDP connections in FIPS mode if destination is
    localhost.
