closes #229

  - `DerefMut` was not delegating to `force_mut()` (contary to the
    by-ref APIs);
  - `Lazy::force_mut` was not taking advantage of exclusive-mutability
    access, and instead paying shared-mutability access. Mainly, in the
    `sync` case, it involved atomic operations which are now skipped.

Fixes #226
