Bug 568612: correct MANIFEST.MF of org.slf4j.binding.log4j12_1.7.30

It imported org.apache.log4j [1.7,2). That doesn't exist.

Add a manual import, and suppress the export. With these changes, the
MANIFEST.MF looks good to me, and the EGit unit tests can be run again
inside Eclipse.

Dependency to org.apache.log4j isn't optional.
