runvar access: Introduce sharing_for_build

Builds don't have so much contingent setup.  We don't track the
runvars; we just rely on the share-* hostflag set in the job.

But selecthost() is going to automatically enable runvar access
control for shared/reused hosts.  So, provide a way to disable that.
