selftests: always install UAPI headers to the correct directory 

Currently the UAPI headers are always installed into the source directory.
When building out-of-tree this doesn't work, as the include path will be
wrong and it dirties the source tree, leading to complains by kbuild.

Make sure the 'headers' target installs the UAPI headers in the correctly.

The real target directory can come from multiple places. To handle them all
extract the target directory from KHDR_INCLUDES.
