Daniel Almeida da123f0ee4 rust: lock: guard: Add T: Unpin bound to DerefMut ...

A core property of pinned types is not handing a mutable reference to
the inner data in safe code, as this trivially allows that data to be
moved.

Enforce this condition by adding a bound on lock::Guard's DerefMut
implementation, so that it's only implemented for pinning-agnostic
types.
