Subject: selftests: add and export a kernel uapi headers path

Kernel uapi headers can be present at different paths depending upon how
the build was invoked.  It becomes impossible for the tests to include the
correct headers directory.  Set and export KHDR_INCLUDES variable to make
it possible for sub make files to include the header files.
