gnu: Update python-rdflib to 7.0.0.

* gnu/packages/rdf.scm: Add updated recipe for python-rdflib; Keep
  python-rdflib-6 for compatibility.
* gnu/packages/python-xyz.scm: Build python-prov with python-rdflib-6 because
  rdflib-7 is not supported.
* gnu/packages/bioinformatics.scm: Build cwltool with python-rdflib-6 because
  it fails to build with rdflib-7.
