selftests: sched: Fix incorrect kernel headers search path

2023-02-13T16:09:45+00:00

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=...).
