bitbake: bitbake-worker child process create group before registering SIGTERM handler
The bitbake-worker child on the SIGTERM signal handling send the SIGTERM to all
processes in it's process group. In cases when the bitbake-worker child got
SIGTERM after registering own SIGTERM handler and before the os.setsid() call
it can send SIGTERM to unwanted processes.
In the worst case during SIGTERM processing the bitbake-worker child can be in
the group of the process that started BitBake itself. As a result it can kill
processes that not related to BitBake at all.
