Enforce camera shutter sounds to always play for some markets
Carrier requirements in some markets require that the camera shutter
sound is always audible. Our existing build-agnostic approach relies
on MCC, which is only available with a SIM inserted.
For more complete coverage, force shutter sounds on for all devices with
radio.subtype of 1.
Test: First set device to Japan radio mode:
fastboot oem set_platform_info s s 1
Then verify that after muting ringer and media sounds:
- Shutter sounds play in camera app,
no visible setting in app to disable it.
- pdk/apps/TestingCamera also plays shutter sounds.
