This is not the recommended way but it's the only way to get flash light to work but I have to
warn you that it wil prevent your app from entering harbour. You will also have to make use
of resource policy engine to arbitrate access to camera. Failing to do so will lead to breaking
jolla camera app.

Simply replace subdevsrc with droidcamsrc and use droideglsink as the sink and
it should work fine.
