[IIAB] Request for mDNS name resolution from Internet-in-a-Box project

[Samuel Greenfeld]

Looking into this a bit more, what I am seeing may be dependency specific.

If you are lucky enough to have a XO image that has extra items added,
nss-mdns may be present as a dependency.  Otherwise it is not.

I could have sworn this worked at one point in this past though because I
have definitely pinged .local addresses when testing collaboration.
