Switch Bluetooth HAL policy to _client/_server

hal_server_domain must now be used instead of hal_impl_domain.

Test: Add bluetooth_hidl_hal_test to device.mk, build & add to device,
      adb shell stop,
      adb shell /data/nativetest64/bluetooth_hidl_hal_test/bluetooth_hidl_hal_test
      as crashy as before this commit
