openssl cms: add error message if operation option is missing

If the `openssl cms` command is called without specifying an
operation option, it replies with the following laconic error message:

    cms: Use -help for summary.

This commit adds a helpful error message:

    No operation option (-encrypt|-decrypt|-sign|-verify|...) specified.
