1.0.25.10: Fix package locks checks for local functions in the interpeter.

* Package lock checks were being performed in the function binding form's
  body's lexical environment, causing lossage for forms like

  (locally (declare (disable-package-locks foo:bar))
    (flet ((foo:bar ...))
      (declare (enable-package-locks foo:bar))
      ...))

  In particular, this broke some TRACE extensions.
