Subject: selftests: ipc: Fix incorrect kernel headers search path

commit ecf9fdb5c2a9d63c732acccb6318feb73dd1589f 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=...).
