TIF: enable check self-permission for tuner resource access

The current permission check might fail when there are two hardware
inputs trying to obtain the same device id. When this happens, TvInputHardwareManager
will call trm to compare client priority. As TvInputHardwareManager is
in system process, the client pid will be system process, causing the
permission check to fail.
