[Piglit] [PATCH] framework: make the interpret_result method for native tests faster

[Dylan Baker]

This reimplements the interpret_result method of PiglitBaseTest (which
is used by all native piglit tests) to loop once rather than twice.
There is a speedup of about 3 seconds for 10,000 iterations. Being that
piglit runs about 30,000 tests that is something, for a pretty
reasonable patch.
