Subject: events: devices: Mark all uhid virtual devices as external
This driver is currently used for Bluetooth LE, and should be marked
external. Since it's a virtual device it's organized a bit differently.
Terminate and return INPUT_DEVICE_EXTERNAL if we hit the "uhid" device
itself.
BUG=470888
TEST=Ran uhid-example on link to create such a device,
& verified it is detected as external.
