avoid final trailing comma for enum lists

as detected in #485 by @JoachimSchneider.

Refactored the c_standards tests
so that these issues get automatically detected in CI tests.

-  If your application requires interoperability, it's recommended to use it.
-  A library is provided to take care of it, see lz4frame.h.
