zeroconf: forward all arguments passed to ui.configitems() wrapper

f43988e5954c added 'ignoresub' argument to ui.configitems(), but zeroconf
wrapper wasn't updated. It caused the following crash:

  Traceback (most recent call last):

We have no test coverage for zeroconf, so I've added a minimal test that
could reproduce this problem.

#require test-repo pyflakes

  $ cd "`dirname "$TESTDIR"`"

run pyflakes on all tracked files ending in .py or without a file ending
(skipping binary file random-seed)

  $ hg locate 'set:**.py or grep("^!#.*python")' 2>/dev/null \
