Elias Naur d942bdc913 libcamera: v4l2_device: openat(2) with O_CLOEXEC to cleanup after exec(3) 
When an executable using libcamera calls exec(3) while a camera is in
use, file descriptors corresponding to the V4L2 video devices are kept
open has they have been created without O_CLOEXEC. This results in the
video devices staying busy, preventing the new executable from using
them:

[91] ERROR V4L2 v4l2_videodevice.cpp:1047 /dev/video0[149:cap]: Unableto set format: Resource busy

Fix this by opening video devices with O_CLOEXEC, which is generally a
good idea in libraries.
