Allow sharing of local binaries between unrelated boards.

Currently we only share binhosts between a variant and its base board,
because of bug 200417. Now that that bug is fixed, we can remove this
restriction.

Note: While this CL enables the sharing of binaries, there are currently
no builders that would use it, because all of the grouped builders
currently only deal with a single base board. This will change in a
followup CL.

BUG=chromium:348226
TEST=Run with CL to build multiple boards on the same builder.
