Add factory-reset feature to security image as well

The factory-reset-helper package is conditionally appended to IMAGE_INSTALL only in cip-core-image.bb[1].

But the security image uses cip-core-image-security.bb as the top-level image recipe and therefore does not include the factory-reset-helper package.
