[igt-dev] [PATCH i-g-t] lib: Ignore runner's SIGQUIT from fork helpers

[Chris Wilson]

We would rather not confuse our debug our without simultaneous delivery
of SIGQUIT to the helper processes, leaving the parent to handle SIGQUIT
and kill the children. (If the parent is unable to quit, then it and the
children will be killed by the runner.)
