Check build.xml files to ensure they fail fast when one of their targets fail

[smlambert]

This came up in context of JavaTestUtil.java failed to compile, but we continued on to try and run tests. See: https://github.com/adoptium/aqa-tests/blob/master/jck/build.xml

We should check all build.xml files in this repo and add failonerror="true" in targets that need it, much like was done in https://github.com/adoptium/aqa-tests/pull/2179

Noting that the build-jtrunner target which is how JavaTestUtil is compiled has failonerror="true" set, looking at if it propagated properly.
