The version 0.22.3 of python-m2crypto fails to work after
swig updated to 3.0.5+:
AttributeError: 'module' object has no attribute 'PKCS5_SALT_LEN'
It's fixed since 0.22.4 and we could update it to latest version,
but docker-registry depends on the version 0.22.3, so backport
the patch to fix the issue with swig 3.0.5.
