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.

  $ hg init t
  $ cd t
  $ cat > unix2dos.py <<EOF
  > import sys
  > 
  > for path in sys.argv[1:]:
  >     data = open(path, 'rb').read()
  >     data = data.replace(b'\n', b'\r\n')
  >     open(path, 'wb').write(data)
  > EOF
