heimdal: handle referrals for 3 part DRSUAPI SPNs
This handles referrals for SPNs of the form
E3514235-4B06-11D1-AB04-00C04FC2DCD2/NTDSGUID/REALM, which are
used during DRS replication when we don't know the dnsHostName of the
target DC (which we don't know until the first replication from that
DC completes).
We use the 3rd part of the SPN directly as the realm name in the
referral.
