dependency_cross_matcher.py: Compatibilize parsec and parsec-tool

parsec and parsec-tool share some dependencies. In those shared
dependencies, the used versions should be the same.

 * Modify utils/dependency_cross_matcher.py to cover the case of
   comparing parsec and parsec-tool dependencies as well as the
   previous case of checking mismatches in parsec-tool dependencies.
