selftests: mount_setattr: Fix incorrect kernel headers search path

commit 5d11f2d0eb39d2b5c5e8f05e1f650c4a4de69918 upstream.

Use $(KHDR_INCLUDES) as lookup path for kernel headers. This prevents
building against kernel headers from the build environment in scenarios
where kernel headers are installed into a specific output directory
(O=...).
