selftests: add headers_install to lib.mk
If the kernel headers aren't installed we can't build all the tests. Add a new make target rule 'khdr' in the file lib.mk to generate the kernel headers and that gets include for every test-dir Makefile that includes lib.mk If the testdir in turn have its own sub-dirs the top_srcdir needs to be set to the linux-rootdir to be able to generate the kernel headers.
