v4l2: Provide libcamerify wrapper script
Support easier usage of the v4l2 compatibility layer with a script that
handles the LD_PRELOAD for applications.
The wrapper can be prefixed to launch any application with the preload
set:
$ libcamera-v4l2 v4l2-ctl --list-devices
\_SB_.PCI0.GP13.XHC0.RHUB.PRT4- (libcamera:0):
/dev/video0
platform/vimc.0 Sensor B (libcamera:1):
/dev/video2
/dev/video3
/dev/video4
Specifying '-d' once before the command to run will enable V4L2Compat
layer debug output from libcamera.
Specifying '-d' twice will enable all debug levels from all libcamera
components and provide a very detailed log for analysis.
