drm/i915/selftest_hangcheck: Check sanity with more patience
While trying to reproduce some other issues reported by CI for i915
hangcheck live selftest, I found them hidden behind timeout failures
reported by igt_hang_sanitycheck -- the very first hangcheck test case
executed.

Those request waits, once timed out after 100ms, have never been
confirmed to still persist over another 100ms, always being able to
complete within the originally requested wait time doubled.
Taking into account potentially significant additional concurrent workload
generated by new auxiliary drivers that didn't exist before and now are
loaded in parallel with the i915 module also when loaded in selftest mode,
relax our expectations on time consumed by the sanity check request before
it completes.
