    init-ifupdown: add RDEPENDS on ifupdown

    The 'ifup' command provided by 'busybox' and 'ifupdown' behave differently
    when an interface has been configured:

    - The one from busybox
    $ sudo ifup lo; echo $?
    RTNETLINK answers: File exists
    1

    - The one from ifupdown
    $ sudo ifup lo; echo $?
    ifup: interface lo already configured
    0

    The exit code 1 from the busybox one would cause the networking service
    failed, so add RDEPENDS on ifupdown to avoid using the one from busybox.
