nit in qpidd: diagnostic to stderr, not to stdout

[Jim Meyering]

This change makes qpidd write a diagnostic to stderr, not stdout.
This demonstrates the problem:

  $ src/qpidd -9   2>/dev/null
  Warning: skipping unrecognised option -9
  WARNING: Persistence not enabled, no recovery of queues or messages.
  Listening on port 5672...

IMHO, qpidd should fail in that case, too.
