Joseph Sutton c0395578c5 CVE-2022-2031 s4:kdc: Add MIT support for ATTRIBUTES_INFO and REQUESTER_SID PAC buffers
So that we do not confuse TGTs and kpasswd tickets, it is critical to
check that the REQUESTER_SID buffer exists in TGTs, and to ensure that
it is not propagated to service tickets.

BUG: https://bugzilla.samba.org/show_bug.cgi?id=15047

Signed-off-by: Joseph Sutton <josephsutton@catalyst.net.nz>

[jsutton@samba.org Brought in changes to add ATTRIBUTES_INFO and
 REQUESTER_SID buffers to new PACs, and updated knownfails]

[jsutton@samba.org Adjusted MIT knownfails]
