r4673: Fix the IDL for the QuerySecret LSA call.

r4673: Fix the IDL for the QuerySecret LSA call.

This call uses a new IDL type, NTTIME_hyper.  This is 8-byte aligned,
as the name suggests.

Expand the QuerySecret LSA calls in RPC-SAMLOGON and RPC-LSA, to
validate the behaviour of times, and of the old secrets.

Thanks to tridge for spotting the use of HYPER!
