Also add a test of BundleUtilities including an exe,
some shared libs, a plugin, and a framework-style lib.
This test presently runs (and this functionality works)
on Linux, Mac and Windows.
For now, the framework-style lib is built as a plain old
shared lib because there is another yet-unresolved issue
with local frameworks without rpaths on the Mac.
