Remove pkinit-anonymous command
Ever since from v4.5, FreeIPA expects at least some kind of
anonymous PKINIT to work. The pkinit-anonymous command was supposed
to enable/disable anonymous pkinit by locking/unlocking the
anonymous principal. We can't allow this for FreeIPA to work
so we are removing the command as it was never supported anyway.
