To remove all intel-libdrm code in intel_batchbuffer we need to rewrite
and drop it in all dependent code. Currently CI doesn't exercise this
test and I don't have DisplayLink hardware so this is blind rewrite
(instead of removing the test). Common xf86drmMode calls are left
intact as igt likely won't remove libdrm totally.
