This tests the various parts of atomic that I want to make
interruptible. Running with --debug shows the stats from
__igt_sigiter_continue, which can be used to make sure that
we don't fall over.

The default igt kms helpers use drmIoctl, which is not intercepted
by igt_while_interruptible. Only igt_ioctl is. This means we have
to call the ioctls manually here.

Changes since v1:
- Implement interruptible DPMS checking too.
- Use igt_ioctl + igt_while_interruptible, instead of the signal helper
  shotgun.
