python-m2crypto: Error fix for swig >= 3.0.5

After swig upgrade to 3.0.6, build the recipes which
depends on python-m2crypto will occur errors like this:
"SALT_LEN = m2.PKCS5_SALT_LEN
AttributeError: 'module' object has no attribute 'PKCS5_SALT_LEN'"

+Subject: [PATCH] M2Crypto: Error fix.
+
+After swig upgrade from 3.0.2 to 3.0.6,build the recipes which
+depends on python-m2crypto will occur errors like this:
+SALT_LEN = m2.PKCS5_SALT_LEN
+AttributeError: 'module' object has no attribute 'PKCS5_SALT_LEN'
+since python-m2crypto depends on swig-native
