[Intel-gfx] [igt PATCH] configure.ac: require libdrm >= 2.4.75 for I915_EXEC_FENCE_OUT

[Jani Nikula]

I915_EXEC_FENCE_OUT was added in libdrm commit a3d715ee14b2 ("Import
uapi/i915_drm.h from v4.10-rc5-950-g152d5750dda9") and released in
libdrm-2.4.75.

I'm probably doing something wrong. This passes configure for me, but
build still fails with:

gem_latency.c: In function ‘setup_latency’:
gem_latency.c:290:16: error: ‘I915_EXEC_FENCE_OUT’ undeclared (first use in this function)
