Alice Ryhl 8f65291dae rust: sync: Add accessor for the lock behind a given guard ...

In order to assert a particular `Guard` is associated with a particular
`Lock`, add an accessor to obtain a reference to the underlying `Lock`
of a `Guard`.

Binder needs this assertion to ensure unsafe list operations are done
with the correct lock held.
