As described in #4996, Docker 25+ changes made sub-mounts of the /dev
filesystem to be mounted read-only. Revert to the previous behavior by
adjusting the ReadOnlyNonRecursive option. Cleaner way would be to
upstream support for setting this option via Mount class arguments, so
this change is meant to be rather a hotfix for the issue. Even better
approach would be mounting /dev non-recursively, and taking care of
creating all necessary filesystems when creating containers in
Supervisor.
