Minor cygrunsrv nit: --help should go to stdout, not stderr

[Daniel Colascione]

Currently, cygrunsrv --help dumps output to standard error. This
behavior is a slight annoyance because it results in cygrunsrv --help |
less not being very helpful. Can cygrunsrv --help dump its output to
stdout instead?
