r9603: allow the LOCAL-PAC test to use keys and pac data from the command line

For example:

bin/smbtorture //xx/y LOCAL-PAC --option 'torture:pac_file=x.dat' --option 'torture:pac_kdc_key=B286757148AF7FD252C53603A150B7E7' --option 'torture:pac_member_key=D217FAEAE5E6B5F95CCC94077AB8A5FC'
(This used to be commit e0978ead23c493a802ce69ed7be871b2a9a54498)
