Add permission to protect data when sending broadcast

This CL before, DevicePickerFragment didn't check the
whether 3rd-party app have Bluetooth permission before
sending broadcast. It's will cause the 3rd-party app can
get Bluetooth device information without request permission.

This CL will send broadcast with Bluetooth permission that
make sure the receiver who have Bluetooth permission can get
this Bluetooth device infomation.
