selftests: sched: Fix incorrect kernel headers search path

2023-03-10T08:34:15+00:00

commit 0d2cace5af50806a6b32ab73d367b80e46acda0f 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=...).

Previously, 'make -C sched run_tests' will block forever when it occurs something wrong where the *selftests framework* is waiting for its child processes to exit.
