Makefile: add headers_install to kselftest targets

Add headers_install as a dependency to kselftest targets so that they
can be run directly from the top of the tree.  The kselftest Makefile
used to try to call headers_install "backwards" but failed due to the
relative path not being consistent.

Now we can either run this directly:

  $ make O=build kselftest-all

or this:

  $ make O=build headers_install
  $ make O=build -C tools/testing/selftest all

The same commands work as well when building directly in the source
tree (no O=) or any arbitrary path (relative or absolute).
