networkctl: return error or warning when interfaces are not matched

Browse Source 
We'd just print nothing and exit with 0. If the user gave an explicit
name, we should fail. If a pattern didn't match, we should at least warn.

$ networkctl status enx54ee75cb1dc0a* --no-pager && echo $?
No interfaces matched.

$ networkctl status enx54ee75cb1dc0a --no-pager
Interface "enx54ee75cb1dc0a" not found.
