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)
