    gps: Add loc_eng_set_privacy function to enable/disable GPS privacy lock.

    Privacy lock is enabled on loc_eng_init, disabled on loc_eng_cleanup,
    mimicking the behavior of TW.

    The privacy lock state is non-volatile, and control of the lock is needed
    to ensure that the GPS works and is responsive to requests.  Otherwise the
    GPS may silently cease to work depending on its last state in TW.
