drm/i915: fix header test with GCOV
$(CC) with $(CFLAGS_GCOV) assumes the output filename with .gcno suffix
appended is writable. This is not the case when the output filename is
/dev/null:
HDRTEST drivers/gpu/drm/i915/display/intel_frontbuffer.h
/dev/null:1:0: error: cannot open /dev/null.gcno
HDRTEST drivers/gpu/drm/i915/display/intel_ddi.h
/dev/null:1:0: error: cannot open /dev/null.gcno
make[5]: *** [../drivers/gpu/drm/i915/Makefile:307:
drivers/gpu/drm/i915/display/intel_ddi.hdrtest] Error 1
make[5]: *** Waiting for unfinished jobs....
make[5]: *** [../drivers/gpu/drm/i915/Makefile:307:
drivers/gpu/drm/i915/display/intel_frontbuffer.hdrtest] Error 1
Filter out $(CFLAGS_GVOC) from the header test $(c_flags) as they don't
make sense here anyway.
