Retroarch, Lumia 950XL and Bluetooth

[namibiz]

Hi. I'm testing version 1.10.3 on a Lumia 950 XL and I've found an issue with Bluetooth.

I've paired a Xbox Controller and a generic joystick via Windows Phone OS Bluetooth option, but Retroarch don't recognized them, even with all combinations of Input (sdl2, uwp and xinput) and Controller (xinput, sdl2 and hid) drivers. Also, if I try to open the Bluetooth menu inside Retroarch with the bluetoothctl driver, Retroarch close unexpectedly.

Thanks for working on this version and regards.
