Bug 462201 - Remove support for building Eclipse 2.x-style plug-ins

Removes dependency on o.e.runtime.compatibility bundle and removes all
dead code resulting from no longer supporting old-style plug-ins.

Only thing that remains is the "buildingOSGi" option in the buildscript
generator ant task, which is deprecated and de-implemented instead of
removed so as not to break any existing scripts. This should also be
removed in the future.
