Fixing OSGi distribution.

There was some kind of wierd filesystem issue where ANT would overwrite
jars or not, depending on timestamps.  It was a non-repeatable failure.
Rather than overwrite JARs and rely on ANT, let's just spell out the
non-OSGI bundles.  While I had hoped to avoid hard-coding these,
it's probably best we've done so.
