tools: Split fwk and module tests

Currently the ci_cmake scripts execute framework test and
modules' unit tests from the same test case.
The result is shown as below:

Check framework: Success/Failed

This does not tell the user whether the result came from the
framework tests or the unit tests.
Improve this by splitting the two tests and provide detailed
results. The summary will then be as follow:

Check framework: Success/Failed
Check utest: Success/Failed
