Fix manifest metadata to contain only the one applicable
The current jars files of Sat4j used as osgi bundles or as executable jar files are currently sharing the same static manifest files.
The osgi bundles are generated using maven.
The executable jar files using ant.
The latter requires a classpath entry which currently generates warnings in eclipse build (see issue 146).
To avoid this, the manifest files should be adapted to the target usage of the jar files.
