Prevent java.awt.HeadlessException on Windows on TeamCity

[labkey-tchad]

Rationale

On Java 25, tests running on Windows agents are complaining that the application needs desktop access.

java.awt.HeadlessException:
The application does not have desktop access,
but this program performed an operation which requires it.

We can "lie" and tell it that the environment is not headless by setting the java.awt.headless system property.
