Shared library without SO version which is not allowed

[glaubitz]

aws-c-cal currently does not have an SO version despite being a shared library.

However, this is not allowed according to spec as SO versions are mandatory for shared libraries.

Please see the full explanation that I gave for aws-c-common here: awslabs/aws-c-common#698
