msm8660: move Camera overlay to Gallery2 and clean up

  * Remove hasSamsungCamSettings: this was a NOOP in cm-10.1 and
    jellybean. Apparently we have not needed this :)
  * Remove resetVideoRotationParameter: not implemented in cm-10.1
    with no ill effects. Instead of porting the hack forward,
    remove the overlay.
