tests/i915/i915_hangman: Configure engine properties for quicker hangs

Some platforms have very long timeouts configured for some engines.
Some have them disabled completely. That makes for a very slow (or
broken) hangman test. So explicitly configure the engines to have
reasonable settings first.
