[remoting][android] Add gsf.permission.READ_GSERVICES

The "Send Feedback" button in the app no longer works and according to
the logs it seems we need to add gsf.permission.READ_GSERVICES
permission to the Android manifest.

I can't build and test the official build locally so I'd like to check
this in frst then verify it on the nightly build.
