manager: comprehensively mark manager_dispatch_user_lookup_fd() as static

The prototype was static, but the implementation was not. Make both
static, this is otherwise too confusing. (This doesn't actually change
anything, since the prototype decides about this anyway, but it makes
things easier to read.)
