[OE-core] [RFC PATCH v2] Allow remote sstate cache fetches when BB_NO_NETWORK set

Originally I had two changes, on to oe-core's sstate.bbclass and one in
bitbake's fetcher. Following on from the feedback on the bitbake-devel list,
here's version two, isolated to sstate.bbclass.
My objective here is to support a very specific scenario. I have a well-fed
sstate cache on my internal network. I want to use it for accelerating builds
across a variety of machines where NFS is not really an option. I don't want
bitbake to ever attempt to fetch sources for packages, though, so I'm always
using BB_NO_NETWORK.
The proposal I have is adding a new local.conf variable that will allow cache
fetches only to be exempt from BB_NO_NETWORK restrictions. If it is set and
BB_NO_NETWORK is not set, there's no change in behaviour. If it is not set and
BB_NO_NETWORK is set, again, no change in today's behaviour. If both are set,
however, for sstate mirror fetch attempts we will temporarily mask off
BB_NO_NETWORK, allowing the fetch to complete for the sstate object, but still
disable network access for remote sources.
