[PATCH v4 1/2] libcamera: process: Use _exit in child process

[Paul Elder]

Quoting Julien Vuillaumier (2025-05-28 00:56:14)
> Use _exit() in child process in case of execv() error. That is to
> avoid interfering with the parent process as exit() may call its
> atexit() handlers and flush its io buffers.
