procutil: redirect ui.fout to stderr while stdio is protected

The new behavior seems slightly nicer as we can at least read the output.
And this is similar to what the sshserver is doing, so we can probably
reuse protectstdio() instead of the weird hook.redirect(True) hack.

run commandserver in commandserver, which is silly but should work:

  low-level stdout fd and
  stdout should be redirected to stderr
