testenvSettings.sh should only run once

[llxia]

When USE_TESTENV_PROPERTIES=true and DYNAMIC_COMPILE=false, testenvSettings.sh gets triggered twice - once in compile.sh and once before make <test>. This does not cause any issues, but it is not necessary.

We should add an if statement in https://github.com/adoptium/aqa-tests/blob/83bec274a10eb52ac812af2acc50bb3ec4bc4673/buildenv/jenkins/JenkinsfileBase#L9

run . ./scripts/testenv/testenvSettings.sh only if DYNAMIC_COMPILE == true
