Revert "Remove %autopatch which is not needed"
    
    This reverts commit d0313930ec0263ecc68e88f56052de64272a02f3.
    
    “%autopatch -p0” is actually needed, removing it had the effect that
    the patches are not applied anymore.
    
    There used to be
    
    “%autosetup -p0” in the “%prep” section which applied the patches but
    I replaced this with “%autosetup -N” which does not apply the patches
    and added “%autopatch -p0” after unpacking the inscript2 and m17n-db-sayura
    tarballs to make it possible to apply patches to the contents of these sources
    as well.
    
    m17n-db-1.8.0-inscript2-mni-sat.patch needs to be applied to the
    inscript2 tarball.
