aux: Suspend signal helper for shell commands
The clone() system call with a larger executable (like /bin/sh) may have
difficulty to make progress on some platforms if interrupted frequently.
So suspend the signal helper process for the duration of the syscall.
This is needed to solve an actual problem by the next patch.
v2:
- Clarify/fix code comments. (Chris)
- Update igt_system_quiet() as well accordingly.
