Fix "make test" failing on missing "test-unit"
Fix "make test" failing on missing "test-unit"

Commit dbf580be57a4bb854d7ce20d313e3a22ea337be5 removed
this helper script because it's no longer used in CI.

However, the "make test" target in the Makefile still
called this helper, resulting it to fail.
