Exclude log4j and packages from target-test-runner

This is intended to fix https://trac.openmicroscopy.org.uk/ome/ticket/12114.  Running ```ant clean jars tools``` and then ```cd components/test-suite && ./target-test-runner loci.tests.testng.OpenBytesPerformanceTest /path/to/test/file``` should produce more ```*.log``` files in ```components/test-suite``` than the same command without this PR merged.

It's also important to verify that the performance builds remain green with this PR included.
