Fixes build script dependency building

* Updates the repo to point to the new commits on the sub-modules relating
  to fixing the build script dependency issue.

* Comments on sub module commits
 * For mvn process-sources to work correctly in eclipse, it is necessary to
   also build the org.teiid.datatools plugins. If these have not been
   previously built in the local mvn repo then the auto-builder in Eclipse
  fails.

 * This is annoying since these plugins are only required for the tycho TP
   which is not even executed during the process-sources phase. An Eclipse
   bug is currently open for this issue at
   https://bugs.eclipse.org/bugs/show_bug.cgi?id=353889

 * Removes the unnecessary generate-javacc profile since it is no longer
   used or initiated.
