Bug#839819: quagga should not wait for network-online.target

[Hirotaka Yamamoto <ymmt2005@gmail.com>]

Package: quagga
Version: 1.0.20160315-2

The current rc script for quagga has "$network" as:

    /etc/init.d/quagga:# Required-Start: $local_fs $network $remote_fs $syslog
    /etc/init.d/quagga:# Required-Stop: $local_fs $network $remote_fs $syslog

systemd treats services having $network in their rc scripts just as having

    Wants=network-online.target
    After=network-online.target

Details are described in
https://www.freedesktop.org/wiki/Software/systemd/NetworkTarget/

Since quagga is used to maintain network routing information, and
network-online.target
is a target after which networking including routing is ready to use,
/etc/init.d/quagga
should not contain "$network".

Please remove them.
