xl/libxl: treat vif "ip" fields as a simple string
Currently we parse the string as an IPv4 address but this does not
handle IPv6. We then format the IP address as a string into xenstore.
Rather than add further parsing and formatting to support IPv6 simply
treat the field as a string, which it turns out is all xend does.
