[Intel-gfx] [PATCH] drm/i915: rename header test build commands to avoid conflicts

[Jani Nikula]

We have a local hack to test if headers are self-contained, while
upstreaming a proper generic solution in kbuild [1]. Now that both have
found themselves in linux-next, the identical cmd_header_test build
commands conflict, leading to errors such as:

>> drivers/gpu/drm/i915/header_test_intel_audio.c:1:10: fatal error:
>> drivers/gpu/drm/i915/intel_audio.h: No such file or directory
    #include "drivers/gpu/drm/i915/intel_audio.h"
	     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Rename the i915 local build command until the proper kbuild solution
finds its way to Linus' master and gets backported to our tree, and we
can finally switch over.

Note that since the kbuild header test requires CONFIG_HEADER_TEST=y,
and our hack requires our debug option CONFIG_DRM_I915_WERROR=y, this is
likely hit only by build test bots.
