Fix for missing classes in jar with bnd-produced manifest

[scottslewis]

Fixes problem with previous pull request for issue_521.

Does this by removing includes section from annotation/pom.xml maven-jar-plugin configuration. On clean install, all classes plus correct manifest present in the snapshot jar.

The bnd-generated manifest from snapshot jar is:

I've verified that this is a properly-formatted bundle via bndtools. Also verified that a compile of all smallrye-common projects completes with the newly built annotation jar.
