fabc04a4d9 ci: Keep system env vars as-is (MarcoFalke)
fa8dcdcc8b ci: Set PATH inside the CI env (MarcoFalke)
fac229ab1f ci: Remove P_CI_DIR and --workdir (MarcoFalke)
Pull request description:
This fixes a bug where the `$PATH` from the host is used inside the container. This will lead to bugs when the `$PATH` is different. For example on a host of Fedora 38, and a container of `debian:bullseye`.
This can be tested with the `FILE_ENV=./ci/test/00_setup_env_arm.sh` CI env. On master:
```
Error: crun: executable file `bash` not found in $PATH: No such file or directory: OCI runtime attempted to invoke a command that was not found
```
