zeroconf: fix boolean return value

This was (wrongly) flagged by Pytype as being undefined since it doesn't
seem to understand `try` blocks. However, the caller is expecting a boolean
and the fix to appease Pytype is simple, so we do both.

Tests if hgweb can run without touching sys.stdin, as is required
by the WSGI standard and strictly implemented by mod_wsgi.
