gpu: run a single representative scene per tool by default

Browse source 
glmark2 (terrain) and vkmark (texture) now each run one ~10s scene instead of
the full multi-scene sweep, cutting the headed part to about a minute. Scene
seconds and the vkmark scene are tunable via GLMARK2_DURATION, VKMARK_DURATION
and VKMARK_BENCH.
