[ruby/rubygems] Unlock every locked spec when an :all override is present

An :all override applies to every gem's metadata, so we have no way to
know which locked entries it affects without re-resolving. Force-unlock
them all when an :all override appears so the resolver gets a fresh
chance to apply the override.
