    umdns: remove superfluous include in init script
    
    The umdns init script includes function/network.sh globally, outside of any
    service procedure. This causes init script activation to fail in buildroot
    and IB context if umdns is set to builtin.
    
    Additionally, the network.sh helper is not actually used.
    
    Drop the entire include in order to repair init script activation in build
    host context. Fixes FS#658.
