tests/gem_gtt_hog: Fix for BDW

Browse Source 
Update XY_COLOR_BLT command for Broadwell.

v2: stash devid and remove ugly double allocation. (by Chris).
v3: fix inverted blt command size and stash fd, devid and intel_gen.
v4: improved len calculation and noop between blt commands. (by Chris).

Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=73724
