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:

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

  $ hg init
  $ echo 0 > a
  $ echo 0 > b
  $ hg ci -A -m m
  adding a
  adding b
  $ hg rm a
  $ hg cat a
  0
  $ hg cat --decode a # more tests in test-encode
  0
  $ echo 1 > b
  $ hg ci -m m
  $ echo 2 > b
  $ hg cat -r 0 a
  0
  $ hg cat -r 0 b
  0
  $ hg cat -r 1 a
  a: no such file in rev 7040230c159c

  $ hg cat -r 1 b

Test multiple files

  $ echo 3 > c
  $ hg ci -Am addmore c
  $ hg cat b c

  $ hg cat .

  $ hg cat . c
