Do not bundle slf4j static logger binding in weld-servlet.jar

Bundling a static logger implementation with the weld-servlet.jar generates a warning that would not be necessary. The weld-servlet.jar (uber jar) is still (or arguably more) useful without the binding.

Opened this ticket as requested by Pete in response to a forum thread. This could be done similar to WELDSE-12 (requested in this comment). Assumed that WELDX and it successor SOLDER are not the right projects for this request.
