tests/drv_suspend: hibernation test

Browse Source 
intel-gpu-tools currently has a bunch of tests for suspend,
but currently none (that I could find) for hibernate.

Attached is a rudimentary patch to add said test.  It does so
by repurposing the drv_suspend driver to handle both suspend
and hibernate, since the difference is miniscule.

I decided to split the suspend/autoresume functions in
igt_aux.c though, to be able to leave the igt_system_uspend_autoresume()
function unchanged (the other option would be to
introduce a boolean function argument and have that
decide what parameters to pass to rtcwake).

The timeout passed to rtcwake probably needs tuning (it might
even need to be dynamically adjusted, since the time hibernation takes
varies wildly depending on the amount of non-cache memory in use).
