lib: Expand igt_hang_ring() to select target context and various options

Some potential callers want to inject a hang into a particular context,
some want to trigger an actual ban and others may or may not want to
capture the associated error state. Expand the hang injection interface
to suit all.

v2: Disable the new kernel API, but push to provide a missing piece of
infrastucture to unbreak compilation.
