Allow dnsmasq read access to IPv6 config

The IPv6 Neighbor Discovery protocol (RFC 2461) suggests
implementations provide MTU in Router Advertisement (RA)
messages.  From section 4.2

MTU    SHOULD be sent on links that have a variable MTU
       (as specified in the document that describes how to
       run IP over the particular link type).  MAY be sent
       on other links.

dnsmasq supports this option and should have read access
to an interface's MTU.
