arc: Temporary workaround for enabling ARC Kiosk on N.

Kiosk users don't have user prefs, hence the filesystem compatibility info
cannot be stored there. As a tentative remedy, this CL stores the info on
memory in that case.

This hack will become unnecessary once the full migration is implemented
for Kiosk users.
