dns: deprecate passing falsy hostname to dns.lookup#23173

Conversation
We can `dns.lookup` a falsy `hostname` like `dns.lookup(false)` for the reason of backwards compatibility long before(see nodejs#13119 for detail). This behavior is undocumented and seems useless in real world apps. We could also make invalid `hostname` throw in the future and the change might be semver-major. Fixes: nodejs#13119
