Due to the addition of sync::lock::Backend::Context, lock guards can be
returned with a different Backend than their respective lock. Since we'll
be adding a trait bound for Backend to GlobalGuard in order to support
this, users will need to be able to directly refer to Backend so that they
can use it in trait bounds.

So, let's make this easier for users and expose Backend in sync.
