Prep for branding & baselines (#997)

* Use `$(BUILD_SOURCEVERSION)` to determine SHA
- support AzDO CI a bit more directly

nit: use CI properties in repo.targets too

* Use Ubuntu 18.04 build agents
- set locale consistently on all platforms
    - default locale on newer agents is unloved `C.UTF-8`

* Fix failing Tests
- use current runtime version in `InstallDotNetTests`
