boot-qemu.py:216:35: PLW1509 `preexec_fn` argument is unsafe when using threads
preexec_fn is on the path towards deprecation, so workaround this warning by refactoring the code to use the new keyword argument process_group when using Python 3.11 and newer, which makes it clear that we don't need preexec_fn longterm. This conveniently hides the preexec_fn use in Popen() so there is no more warning.
This is the same warning from
