kern-tools: expand kernel features that point to a directory name

Updating the kern-tools SRCREV to pick up the following fix:

    When a feature is passed to the kernel configuration scripts, and that
    feature is a directory name, it is a shortcut for:

      $DIR/$DIR.scc

    This expansion is not commonly used, and should be avoided. But for the
    purposes of backwards compatibility, updateme can expand the feature into
    a .scc file before passing it to the next set of configuration scripts.
