Consider using System.Debug instead of Endjin.BuildDiagnostics

[idg10]

#15 added the ability to dump environment variables by setting a build variable.

In addition to defining a variable to enable this in isolation, Endjin.ShowEnvironment, we also introduced a new Endjin.BuildDiagnostics with the intention of being able to use that to turn on all diagnostics at once.

However, as @MikeLarah has pointed out, it might be better to use the built-in System.Debug variable so that this happens automatically when you check the Enable system diagnostics box when queuing a build.
