build: drop legacy v2 service and simplify build system
This removes -Dagent and just uses -Dtools as it only affects sysprof-cli and sysprof-agent. We still need to patch sysprof-cli for recent changes as we did for sysprof-agent though. Additionally, we haven't used the v2 service in forever, so drop that as I can't imagine anyone has been using it.
