Prefer TCP to UDP for password changes

When password changes are performed over UDP, spotty networks may
cause the client to retransmit.  This leads to replay errors if the
kpasswd server receives both requests, which hide the actual request
status and make it appear that the password has not been changed, when
it may in fact have been.  Use TCP instead with UDP fallback to avoid
this issue.
