Eliminate EBR dependencies and repository config

Swap the following EBR-specific dependencies for their equivalents at
Maven Central:

 - atinject-tck
 - jaxb
 - xmlbeans

Remove the /ebr-maven-external repository from the build script entirely
such that all dependencies are now resolved against a single repository:

    http://repo.springsource.org/libs-release
