scripts/update-linux-header.sh: be more src tree friendly

Browse Source 
Running "install_headers" in the Linux source tree is fairly
unfriendly as out-of-tree builds will start complaining about the
kernel source being non-pristine. As we have a temporary directory for
the install we should also do the build step here. So now we have:

  $tmpdir/
    $blddir/
    $hdrdir/
