Remove logging.properties from vaadin-sass-compiler JAR

The dependency vaadin-sass-compiler-0.9.12.jar (used by nuxeo-web-resources-wro) contains a logging.properties file at the root of the JAR, which overrides any java.util.logging (JUL) configuration contributed by the java.util.logging.config.file system property.

This file should be removed from the artifact we use, in order to allow proper JUL logging if necessary (it's necessary for instance to get Oracle JDBC Driver debugging).

https://github.com/vaadin/sass-compiler/pull/309 is a fix for this, which we should include in a custom patched artifact.
