Make the container to run with the UID and GID of the user running pattern.sh

This allows us to drop the /root bind mount and it will also show any
errors related to paths in the proper folder. E.g. any permission
problem of KUBECONFIG files won't be shown as /root/kubeconfig (inside
the container) but as the proper path inside the /home folder.

Tested on F38, F39, RHEL8.9 and RHEL9.2
