fa5d709fb266c97d4db15006bf855e887a6c123b ci: Move wrap-qemu into separate script (MarcoFalke)

Pull request description:

  Now that the ci system no longer propagates files from the docker container back to the host, the wrap-qemu script is broken.

  To fix it, every statement in the script needs to be executed in the docker (with `DOCKER_EXEC`). Instead of juggling with triple escape sequences like `\\\"`, just move the script to a separate file and call it with `DOCKER_EXEC`.

  Also, fix a bunch of other bugs that prevent running the ci system in qemu

  See the `ci/README.md` on how to test. TLDR: Can be tested with (replace `arm` with `s390x` to run the s390x build):

  ```
  FILE_ENV="./ci/test/00_setup_env_arm.sh" MAKEJOBS="-j9" ./ci/test_run_all.sh
  ```
