runsv: robustify signal handling - SIGTERM to child between vfork and exec could mess things up
While at it, rename bb_signals_recursive_norestart() to bb_signals_norestart():
"recursive" was implying we are setting SA_NODEFER allowing signal handler
to be entered recursively, but we do not do that.
