prerelease test broken if custom CCACHE_DIR is used

[rhaschke]

This build using a custom CCACHE_DIR=/home/runner/work/rviz/rviz/.ccache fails with the following error:

# BEGIN SECTION: Run Dockerfile - build and install
# BEGIN SUBSECTION: build workspace in isolation and install
...
ccache: error: Failed to create directory /home/buildfarm/.ccache/tmp: Permission denied

The CCACHE_DIR is correctly passed to docker run by industrial_ci:

docker create --init --env-file /home/runner/work/_actions/ros-industrial/industrial_ci/master/industrial_ci/src/isolation/docker.env --rm -e TRAVIS -e OS_NAME -e OS_CODE_NAME -e OS_ARCH -e PRERELEASE_DOWNSTREAM_DEPTH -e PRERELEASE_REPONAME -e ROSDISTRO_INDEX_URL -e PRERELEASE_DISTRO -v /tmp/tmp.xNEHYg9fGl:/tmp/tmp.xNEHYg9fGl:rw -e WORKSPACE=/tmp/tmp.xNEHYg9fGl -v /run/docker.sock:/run/docker.sock:rw -v /home/runner/work/rviz/rviz/.ccache:/tmp/tmp.xNEHYg9fGl/home/.ccache:rw -e CCACHE_DIR=/tmp/tmp.xNEHYg9fGl/home/.ccache -v /home/runner/work/rviz/rviz:/home/runner/work/rviz/rviz:ro -e TARGET_REPO_PATH=/home/runner/work/rviz/rviz -v /home/runner/work/_actions/ros-industrial/industrial_ci/master/industrial_ci/src:/home/runner/work/_actions/ros-industrial/industrial_ci/master/industrial_ci/src:ro -e ICI_SRC_PATH=/home/runner/work/_actions/ros-industrial/industrial_ci/master/industrial_ci/src -v /home/runner/work:/home/runner/work:rw -e BASEDIR=/home/runner/work -v /home/runner/work/_temp/_runner_file_commands/set_output_f3392e2a-41ca-442c-8479-71cfa390e1c6:/home/runner/work/_temp/_runner_file_commands/set_output_f3392e2a-41ca-442c-8479-71cfa390e1c6:rw -e GITHUB_OUTPUT=/home/runner/work/_temp/_runner_file_commands/set_output_f3392e2a-41ca-442c-8479-71cfa390e1c6 -t --entrypoint -w /home/runner/work/rviz/rviz ros:noetic-ros-core /bin/bash /home/runner/work/_actions/ros-industrial/industrial_ci/master/industrial_ci/src/run.sh ros_prerelease run_ros_prerelease

This used to work 8 months ago.
I'm afraid that's a bug introduced by the upstream prerelease scripts, but I don't have time now to investigate 😞

#870 uses the latest ros_buildfarm version, which might have improved CCACHE_DIR support
