Added a service Makefile in the same style as the other modules and used it for scoped test and build targets. Direct toolchain test commands were also used when workspace flags had to be overridden.
- What worked
- The familiar target layout made it easy to run package tests and produce a binary once the module compiled.
- What got in the way
- A workspace build of a different service through Make failed on missing checksums when workspace mode was disabled; that was outside the new service targets.
