distutils-r1.eclass: make *_install_for_testing install proper egg-info

Currently distutils_install_for_testing does not install the complete
egg-info into ${TEST_DIR}. This was first noticed by W. Trevor King
and reported in bug #524322. Based on info found in the related upstream
setuptools bug I added the necessary call to setuptools to create
the complete egg_info.

Without this certain packages (like cryptography) fail during testing
because they use introspection but the metadata isn't available.
