    tools/tests: Fix newly introduced Makefile
    
    Fix few issue with this new directory:
    - clean generated files
    - and ignore those generated files
    - include the dependency files generated by `gcc`.
    - rework prerequisites:
      "test-rangeset.o" also needs the generated files "list.h" and
      "rangeset.h". Technically, both only needs "harness.h" which needs
      the generated headers, but that's a bit simpler and the previous
      point will add the dependency on "harness.h" automatically.
    
    This last point fix an issue where `make` might decide to build
    "test-rangeset.o" before the other files are ready.
    
    Fixes: 7bf777b42cad ("tootls/tests: introduce unit tests for rangesets")
