keyserv(8): unifdef out __FreeBSD__ and KEYSERV_RANDOM

Browse Source 
This doesn't appear to have some active upstream (and it's a steaming pile of
bad 90s crypto design).  Rip out the completely horrible bits and leave the
only mildly less horrible bits.  The whole thing should probably be deleted; to
the extent it purports to provide a security feature: it doesn't.
