Piwebcam: Enable overriding of camera settings

Also, move the uvc-webcam script to buildroot dir so that we have better
separation between uvc-webcam and its startup logic.

How to override camera settings:

Connect to the ttyACM device and issue
/usr/bin/v4l2-ctl -L | less

Then, create a file called camera.txt in /boot and put all parameters
you want overridden, for example:

auto_exposure_bias=15
