[PATCH 10/34] selftests: gpio: Fix incorrect kernel headers search path

[Mathieu Desnoyers]

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=...).
