Drop the rti_license.dat requirement from the release scope build

The release validation scope (TetraIF, Z/src, Lts/Common +
TrainingAreaBase) never consumes an RTI license: no CMake file or
build step reads RTI_LICENSE_FILE, and the only RTI Connext DDS
consumers are all behind BUILD_RTI (OFF for this branch, stubs
compiled instead). The license was pure plumbing:

- new_docker_build.sh: remove the require_file validation, the
  bind mount and the in-container RTI_LICENSE_FILE export
- jenkins-ci-rme: remove the RTI_LICENSE_FILE export and the
  Jenkinsfile workspace-layout comment
- README: document that no license file is needed

Verified with a full pipeline rebuild (scope-rebuild12) run while
rti_license.dat was absent: 0 warnings, ctest baseline unchanged,
all 5 DEBs produced, none of them containing the license.
