guix: python: Switch to python-wrapper as the default version for the python

build system (switches to Python 3) and compute python-version instead of
  passing it as a parameter.

* guix/build-system/python.scm (default-python): Switch to python-wrapper.
* guix/build-system/python.scm (python-build): Drop parameter #:python-version.
* guix/build/python-build-system.scm (wrap): Compute python version from input.
