Grab passenger ver even it's not first line

For https://github.com/capistrano/passenger/issues/20 , if the version info returned by `passenger -v` is not the first line, the original regular expression will return nil so that error will be raised. This might happen sometime, such as RVM might give a warning when running a command.
