Modify checkfc to check (vnd|hw)service_manager_type.

added checkfc options 'l' and 'v' to verify hwservice_manager_type
and vndservice_manager_type on service context files, respectively.

The checkfc call to verify the new hwservice_contexts files will
be added together with hwservicemanager ACL CLs later.
