Revert "In case of anonymous client principal, use the realm of the server"

This reverts commit 34d2748e9052debc6a061911c2c786b46507b531.  As the
entire working group has apparently forgotten, the KDC-REQ body only
has one realm field.  That's used in an AS REQ for both the server and
client realm .  So, in the anonymous pkinit case, I think we want to
send using a client of WELLKNOWN/ANONYMOUS@REAL_REALM.  Waiting to
hear back from the WG on this.
