Bug#845088: pbuilder: please provide a way to access a local mirror during build (needed for d-i)

I've long be aware of d-i needing access to a local mirror (with the d-i
component available) to build, as it needs to download them during
build.  I'm sure there is a bug somewhere against it, but the consensus
that downloading stuff from a (local, detected by peeking in
sources.list or such) mirror is accepted, as opposed to poke to the
wilder outside net.

As recently confirmed by kibi in #806984#32

I'm not sure how this could be tackled in any way, given that pbuilder
disables access using unshare, but I guess there is a way.
While on it, this could be expanded to "allow access to a defined set of
addresses", maybe.
