Fri Sep 16 16:22:29 UTC 2016
From: Ed Bartosh <ed.bartosh at linux.intel.com>
This function reads pid of runbuilds process from
BUILDDIR/.runbuilds.pid and sends SIGUSR1 to it. signal_runbuilds
function will be used in Toaster code to notify runbuilds when
build is scheduled, finished or cancelled.
