I added only stub versions and fragments by trial and error and got ufp 
running.
Nonetheless, unetmsg is still in a crash loop because in openwrt-23.05 
it wasn't possible
to run:

> function update_acl() {
>        let data = ubus.call(libubus.SYSTEM_OBJECT_ACL, "query");
>        core.acl_set(data.acl);

This is because SYSTEM_OBJECT_ACL was not defined there.

In my opinion it is cleaner to only include unetmsg.client if it is 
marked as dependency and therefore is on the device, because unetmsg 
fails also with stub version of a few functions.
What do you think?
