known failures:
- autotest tests make a bunch of network connections
- chrome gclient hooks fetch stuff

might be worth making it a temporary RESTRICT option so we can disable it in most ebuilds while we lock down the few that need it

ebuild: allow RESTRICT=network-sandbox in ebuilds

Some ebuilds are a bit hard to fix their use of the network in src
phases, so allow them to disable things.  This allows us to turn off
access by default and for the vast majority while we work out how to
fix the few broken packages.

Hopefully we can back this out once all the ebuilds have been updated.

TEST=building an ebuild with RESTRICT=network-sandbox allows network access still

autotest/chrome: allow network access in src phases

Until we can sort out how to make these work w/out network access,
allow it.

going to close this out as the change seems to have stuck.  autotest's statd logic has been purged, but it still has some `git clone` calls in there.  we'll handle that in  issue 741791 .

i'm going to just give up on chrome for now.
