chroot connection plugin: defer get_option() call (#59065)

* The chroot connection plugin crashes because its constructor calls
  self.get_option(...) before the plugin loader has established its
  self._load_name.  Therefore, we should defer the self.get_option(...)
  call so that it happens in connect().

Fixes #59063
