Subject: [PATCH] Do not force the pure Go name resolver

Revert to Go's default mechanism that will decide between the `netgo`
pure-Go implementation and the `netcgo` cgo-based implementation depending
on OS and environment variables.

This allows, among other things, to use Prometheus to scrape mDNS targets.
