Andreas Schneider 5c4afce7bb s4:kdc: Implement samba_kdc_check_s4u2proxy_rbcd()
This will be used by the MIT KDB plugin in the next commits.

A security descriptor created by Windows looks like this:

    security_descriptor: struct security_descriptor
        revision                 : SECURITY_DESCRIPTOR_REVISION_1 (1)
        type                     : 0x8004 (32772)
