Accept '==' operator in cubes dependencies

'==' is the operator used in the python dependencies specifications.
See PEP 440 http://legacy.python.org/dev/peps/pep-0440/#version-specifiers

Using the same operator in cubes dependencies allow to make setuptools handle
the cubes dependencies while keeping cubicweb happy about the dependencies.

Closes #4375144
