Fix persistent folder check within containers

Browse Source 
The previous persistent folder check worked by checking if a file
exists. If you used a bind-mount, then this file is not there. But when
using a docker/podman volume those files are copied, and caused the
container to not start.

This change checks the `/proc/self/mountinfo` for a specific patern to
see if the data folder is persistent or not.

Fixes #2622
