zeroconf: fix an issue concatenating bytes and str
`bytes(length)` doesn't do what we want, so use `str`.
There appear to be a ton more issues in this extension, including:
- globals()[b'_GLOBAL_DONE'] using bytes as the key
- `__author__` and similar using bytes
- `BadDomainName` is feeding bytes to the Exception constructor
- DNSRecord.toString() has the wrong signature (should be str, not bytes)
