Remove the requirejs-dplugins dependency from the full build test.

Use a plugin specifically done for testing instead.

Thanks. On a related note, somewhere you should document the API to write plugins, like your custom addModules() callback.

This is linked to ibm-js/requirejs-dplugins#6. The requirejs-dplugins build tests should be in the requirejs-dplugins repository and the build test of grunt-amd-build should be independant from other projects.
