David Anderson ac009426a0 util/dnsname: don't validate the contents of DNS labels.
DNS names consist of labels, but outside of length limits, DNS
itself permits any content within the labels. Some records require
labels to conform to hostname limitations (which is what we implemented
before), but not all.

Fixes #2024.
