selftests: pidfd: Fix incorrect kernel headers search path

commit 3f7d71768795c386019f2295c1986d00035c9f0f 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=...).
