fixed no DS descriptor generated in some cases

The code only considered direct pom.xml configuration to determine
if projects needed DS descriptor generation or not and did not
generate DS descriptors enabled in included bnd files.

Changed the code to consider both pom.xml and included bnd files
to decide if DS descriptor generation is needed.
