drivers/gpu/drm/i915/gvt/Makefile is included from drivers/gpu/drm/i915/Makefile and thus inherits the normal include path relative to drivers/gpu/drm/i915/. Fix up the gvt-specific trace header and just do away with the include path manipulation.

This is not actually correct. Please see my gvt Makefile cleanup [1][2].
