Bug Description

ifup doesn't trim alias portion of interface from sysctl when configuring IPv6 static addresses:

    # ifup eth0.4000:ucarp
     * Setting up iSCSI targets
       ...done.
    ssh stop/waiting
    ssh start/running, process 23415
    error: "net.ipv6.conf.eth0/4000:ucarp.autoconf" is an unknown key
    Failed to bring up eth0.4000:ucarp.

/etc/network/interfaces:

    iface eth0.4000:ucarp inet6 static
      address 2001:db8::7006
      netmask 64

Note: I'm running uCARP on the IPv4 address family, and expecting it to manage IPv6 address as well via `ifup $IFACE:ucarp` in /usr/share/ucarp/vip-up .

I've tested with /sbin/ifup version 0.7.47.2ubuntu4 copied from a Trusty host and it works fine.
