i-g-t: gem_dummy_reloc_loop.c: add vebox test case

Browse Source 
Aside from adding VEBOX support, this test allows allows the "mixed"
test case variant to work on platforms that have 2 rings which was
previously not the case. To the best of my memory, this might therefore
impact G45, and Ironlake.
