libcamera: media_device: Add functions to lock device for other processes
Add lock() and unlock() which are backed by lockf() and allow an instance of libcamera to claim exclusive access to a media device. These functions are the base of allowing multiple user of libcamera to coexist in the system without stepping on each other's toes.
