criu: build and install wheels

Mimic what we do with python_pep517.bbclass in do_compile (python3 -m build) and
do_install (python3 -m install) to build and install wheels and avoid the heavy
handed pip install usage.

FIXME: even though lib/pycriu/version.py is properly being dynamically generated,
       setuptools/config/expand.py is failing to detect the __version__ attr.

+Subject: [PATCH] crit/pycriu: build and install wheels
+
+Rather than using heavy handed pip (which requires network access to
+fetch the index), mimic what we do in python_pep517.bbclass do_compile
+and do_install for both crit/ and lib/pycriu
