Joseph Sutton abdac4241d CVE-2022-2031 s4:kdc: Reject tickets during the last two minutes of their life
For Heimdal, this now matches the behaviour of Windows. The object of
this requirement is to ensure we don't allow kpasswd tickets, not having
a lifetime of more than two minutes, to be passed off as TGTs.

An existing requirement for TGTs to contain a REQUESTER_SID PAC buffer
suffices to prevent kpasswd ticket misuse, so this is just an additional
precaution on top.

[jsutton@samba.org As we don't have access to the ticket or the request
 in the plugin, rewrote check directly in Heimdal KDC]
