Specify key length for kcapi-enc #150

This issue is similar to #141 .

When working with SM4 algorithm, setsockopt() fails with errno -EINVAL. This is because SM4 supports 16-byte keys only but a 32-byte key is used by kcapi-enc.

An optional solution is to add an option to kcapi-enc to specify key length, imho.

I have created a pull request (#151) for this issue, which adds --key-len option and works well for me. All original tests for kcapi-enc are passed.
