Remove unused dependencies from org.jberet.jberet-core

Analysis of org.jberet.jberet-core shows:

• org.jboss.jts is unused
• jberet only uses javax.enterprise.api, javax.inject.api, javax.annotation.api and javax.batch.api from javaee.api, maybe we could reduce the final size removing javaee.api and add only the required modules.
