bitbake: cooker: Allow upstream for local hash equivalence server

The hash equivalence server has had the option to support a read-only
upstream server for some time now when launched as a standalone program,
but there was no way to set the upstream when using a locally started
server. Add a new variable called BB_HASHSERVE_UPSTREAM that can be used
to specify an upstream server when a local hash equivalence server is
used (e.g. BB_HASHSERVE is "auto")
