fix(Seafile): Misc improvements (#10504)

**Description**

Persisting to the `storage` directory, even if Seafile doesn't show
visible files at least we can seperate this in case people store large
Seafile files on another file.

Added some privilege escalation in case people want to attempt to run
FUSE

Cannot run as `apps` due to init scripts not running
