Clean up scriptlets and dependencies.
    
    The %pre scriptlet had some horrible hack to try and turn on synchronous
    writes if /var was on ext2.  That hasn't been useful for a long time.
    
    cyrus no longer builds static libraries, so don't bother having the
    -devel package provide a -static package.
    
    Scriptlet dependencies were weird across the board; the -utils package
    had scriptlet deps but didn't even have any scriptlets.  Clean all of
    that up.
