libcli/security: fix dom_sid_in_domain()
Ensure the SID has exactly one component more then the domain SID, eg
Domain SID: S-1-5-21-1-2-3
SID: S-1-5-21-1-2-3-4
This will return true. If the SID has more components, eg
SID: S-1-5-21-1-2-3-4-5, or
SID: S-1-5-21-1-2-3-4-5-6-7-8
dom_sid_in_domain() must return false.
This was verified against Windows:
