Allow false positive hits from build-in AABBs intersector

This extends the fix from 7ff1f9cd to 'mixed' tests, which
also use AABBs.

This change allows the test to execute any hit shader,
in case of AABB geometry is used and the ray falsely 'intersects'
it.

This is needed, as the test does not calculate the proper
intersection in 'intersection' stage - it uses a shader that always
reports TRUE. Hence the test relies on build-in AABB
intersector, which may report false positives according to the
specification.
