Add fixed CI action

This fixes the following issues
* Not compiling protoc/lisp plugin properly
* Not correctly outputting a failure when there is a
compile time error

Note that the dependencies "clunit2" and :babel had
to be manually loaded in the call to sbcl. This means
that if cl-protobufs picks up additional dependencies,
they may need to be added here in order for the CI to
work properly.
