The reason resolvconf stops with the lookback address by default is that
in most cases dsnmasq is sufficient to handle all name resolution.  So
another approach to getting your system working would be to add your
hard-coded nameservers to the dnsmasq configuration rather than the
network/interfaces file.

Title:
  resolvconf ignores given dns-servers in /etc/network/interfaces

Status in “resolvconf” package in Ubuntu:
  Invalid

Bug description:
  resolvconf ignores given dns-servers in /etc/network/interfaces if the
  interface in question is configured by dhcp:

  auto em1
  iface em1 inet dhcp
    dns-nameservers 10.161.18.34 10.129.18.34
    dns-search xxx.yy

  the "dns-nameservers"-line is ignored (it shouldn't), while the "dns-
  search"-line is honoured:

  # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
  #     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
  nameserver 127.0.0.1
  search xxx.yy

  Together with dnsmasq handling name resolution no names other tan
  local known ones are resolved.
