Remove org.hamcrest.core from Eclipse SDK

- The org.hamcrest.core bundle is just an empty hull to provide metadata
that redirects all references to it to the new org.hamcrest bundle that
avoids split packages with the org.hamcrest.library bundle by combining
all the content into a single bundle.
- Nothing in the SDK should require org.hamcrest.core anymore, so it can
be removed.
- A new org.junit bundle from Orbit is needed that requires the
org.hamcrest bundle instead of the org.hamcrest.core bundle.
