auth: remember the origin of sids from the PAC

auth: remember the origin of sids from the PAC

So far the conversion from TGT PAC to
struct auth_user_info_dc back to TGS PAC
looses the information in what part of
the PAC_LOGON_INFO a sid was stored.

With this change we let
make_user_info_dc_{netlogon_validation,pac}()
remember this, so that
auth_convert_user_info_dc_sam{baseinfo,info6}()
can rebuild the information into the desired
parts of the PAC_LOGON_INFO.

This was found and fixed for sid filter related
tests, but it turns out that it already
fixes a few tests from samba.tests.krb5.device_tests.

All other places get an implicit AUTH_SID_ORIGIN_UNKNOWN (=0),
which means we use the same logic as before.
