  eni rendering of ipv6 gateways fails

Bug description:
  cloud-init trunk and xenial, yakkety, zesty and artful all fail

  A network config with a ipv6 gateway route like:

  
  subnets:
    - type: static
      address: 2001:4800:78ff:1b:be76:4eff:fe06:96b3
      netmask: 'ffff:ffff:ffff:ffff::'
      routes:
        - gateway: 2001:4800:78ff:1b::1
          netmask: '::'
          network: '::'

  For eni rendering, this should create a post-up/post-down route
  command that generates a default ipv6 route entry, like this:

      post-up route add -A inet6 default gw 2001:4800:78ff:1b::1 || true
      pre-down route del -A inet6 default gw 2001:4800:78ff:1b::1 || true

  However, what is currently generated is this:

      post-up route add -net :: netmask :: gw 2001:4800:78ff:1b::1 || true
      pre-down route del -net :: netmask :: gw 2001:4800:78ff:1b::1 || true

  That does not install the route correctly as a default gateway route.

  This is fallout from commit d00da2d5b0d45db5670622a66d833d2abb907388 
  net: normalize data in network_state object

  This commit removed ipv6 route 'netmask' values, and converted them to
  prefix length values, but failed to update the eni renderer's check for
  ipv6 default gateway.
