Temporarily add GALLERY_PROVIDER permission to fix Beam.

Photo transfers incoming through Android Beam switch processes
twice (Gallery->NFC, NFC->Bluetooth), and the permission to
access to the Gallery content provider is not transferred.
As a short term solution, grant Gallery provider
permissions to Bluetooth.
