gamma_test: add new test
Added new test to test gamma table functionality. It can set linear, negative,
step and exponential gamma table.
The test uses DRM framework also used by atomictest. This change also fixes
the framework to enumerate DRM devices to skip VGEM driver and properly
clears the IOCTL structure before calling buffer alloc.
BUG=chromium:484831
TEST=emerge and deploy drm-tests; stop ui and kill frecon, run gamma_test
