packages/quilt: Add quilt version 0.45, 'cleanup'/complicate layout
    Quilt is the first package we will build, so special care must
    be taken. This is one reason why we do not include/require quilt_${PV}.inc
    directly.
    Now the -native packages require the quilt-native.inc package which
    adds the non-gnu patch for darwin/BSD. In quilt_PV.inc we will aplly
    the basic patches and in quilt.inc we will have all the common stuff
    (like we already had)
    quilt-0.45 does not require the nostrip patch as the file seems to
    be missing.
