libcamera: Open files with O_CLOEXEC
Files opened internally in libcamera without the O_CLOEXEC file will
remain open upon a call to one of the exec(3) functions. As exec()
doesn't destroy local or global objects, this can lead to various side
effects. Avoid this by opening file descriptors with O_CLOEXEC for all
internal files.
