gem_stress: option to disable render copy

Browse Source 
It seems to be randomly broken, every boot in a slightly different
way on my i945gme. Works quite well on my Q35. So add an option to
disable it till this is resolved.

Well, more testing seems to suggest that I've been hunting ghosts.
Or maybe not and it works now simply because it's a different day.
Anyway, leave this in for future testing.
