    tools: xz: use .bz2 archive
    
    In order to build XZ itself we cannot assume that XZ support is available,
    so fetch the bz2 archive variant of its sources instead.
    
    Also drop the FreeBSD portability patch and apply it at prepare time using
    sed, to avoid a dependency on GNU patch which in turn depends on XZ support.
