fa5d709fb2 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
```

Pull request description:
Running the ci completely in a docker, without leaving any traces on the host system is not possible right now because the ccache and depends dir needs to be propagated back and picked up by the host for caching.
