committablefilectx: override linkrev() to point to the associated changectx

This is necessary to annotate workingctx revision. basefilectx.linkrev() can't
be used because committablefilectx has no filelog.

committablefilectx looks for parents() from self._changectx. That means fctx
is linked to self._changectx, so linkrev() can simply be aliased to rev().
