tools/tests: small end-to-end test suite for importing/pruning

As bigger changes lie ahead, we want a small end-to-end test suite
that ensures that our importing and tracing does not fall apart. With
this change, we add the infrastructure and two test-cases (fib, qsort)
including ELFs, traces, and injection results.

In order to run the basic-pruner test cases, one needs to setup a
MySQL table and set the CMake option ENABLE_DATABASE_TESTS.
