Resolves the duplicated resource file aar1JavaResource.txt when building the samples against 544d20d.

Manfred, this is the issue you raised on the Dev list.

As I thought, that failure was due to #426 (mea culpa).
This fixes that by not adding the AAR Java resources to the Maven resource path for the project.

NB unless you also merge #435 you will only be able to build the samples  as far as the next project that uses Proguard. (#435 fixes a problem with ProguardMojo).
