Remove restriction for excluded beanio packages

When using beanio custom type handler with camel-beanio, it needs to access some beanio api, but the Fuse on EAP has restricted the access at the module.xml: 

 <exports>
 <exclude path="org/beanio**"/>
 </exports>

This Jira is to request removing this restriction.  

Reproducer:

mvn clean install
Start Fuse on EAP, and deploy the uploaded "target/example-camel-beanio.war"
