Document the missing OSGI metadata in javax.inject and aopalliance

_From [peerkehendriks](https://code.google.com/u/111602579368504917138/) on March 11, 2011 04:27:26_

The default Guice distro has full OSGI metadata (great!). However the required dependencies javax.inject and aopalliance do not. This still requires the user to manually generate a manifest for these dependencies, or go to a third-party OSGI repo (like Eclipse Orbit) to get the correct jars to install in an OSGI run-time.

Please add the metadata in the default distro so a user does not have to do this by hand. There are preconfigured jars available at: http://download.eclipse.org/tools/orbit/downloads/drops/S20110304120314/
