bug: cannot use file-logger to log to stdout

Current Behavior

When using the file-logger plugin, it is possible to send the logging to stdout by defining /dev/stdout. This in order to use the docker output and relais this in kubernetes to a ELK stack. Though an error is thrown indicating a permission denied for the current user.

Expected Behavior

Be able to use /dev/stdout as a destination with the file-logger plugin.
