lib/aux: Better debug output for rtcwake

Printing the error code is kinda useful. Also tune down the blame
shifting away from i915, this could very well be an i915 bug, not just
a setup issue. Also move the notice to the require test, not the
failure, and suggest to look into dmesg.

v2: Dont print errno, igt_require/assert already do that in the
failure case (Chris).
