aux: Use IGT version of system() call to run rtcwake
The clone() system call has difficulty to make progress if interrupted
frequently by the signal helper process. At least on an APL, like in the
Bugzilla ticket below, this can introduce minutes of overhead to a
single system() call (leading to a global CI timeout). To get rid of the
overhead suspend the signal helper process for the duration of the
system() call, which is provided already by igt_system().
