Fixing serialization compatibility tests for sql tests

The resources files were being loaded using the System
classloader, which is not useful for instrumentation CTS
tests: the app classloader is a direct child of the
boot classloader.

Also moving all sql resources beneath instead of just org.apache.
The resource names used during tests are derived from the
fully-qualified names of the test classes. At build time
we re-package the test code by prepending ""
to the "org.apache" using jarjar. This is probably to
avoid conflicts with other tests / support code that have
been moved to libcore/harmony-tests but retain their
original package name.

Also a small change to the .mk file to remove references
to packages that no longer exist.
