Zygo Blaxell c477618924 crucible: resource: optimize map cleanup ...

We were holding weak refs until the next time the resource ID was used.
This is a bad thing if resource IDs are sparse (e.g. pointers or hashes)
because we'll never see an ID twice.

To fix, determine whether we released the last instance of a resource,
and if so, free its weak ref immediately.
