Jan Scheer a4fc2b5106 who: fix --lookup ... This closes #2181. `who --lookup` is failing with a runtime panic (double free). Since `crate::dns-lookup` already includes a safe wrapper for `getaddrinfo` I used this crate instead of further debugging the existing code in utmpx::canon_host(). * It was neccessary to remove the version constraint for libc in uucore.		2021-05-13 22:16:15 +02:00
