fix Folder-Permissions for `odm2fhir/out/`

[cerbelding]

Expected Behavior

When running the num-node without a FHIR-Server as destination, the JSON files should be saved within odm2fhir/out/.

Actual Behavior

If the folder does not yet exist, the shell-script creates it with an ownership by user root, causing an AccesDeniedException when odm2fhir tries to write files into this folder.

Steps to Reproduce the Problem

1. delete folder odm2fhir/out
2. comment out FHIR_SERVER_URL in odm2fhir/docker-compose.yml
3. run sh 04_execute-odm2fhir.sh
4. see result
