Shannon Sterz 27dd73777f fix #3935: datastore/api/backup: move datastore locking to '/run' ... to avoid issues when removing a group or snapshot directory where two threads hold a lock to the same directory, move locking to the tmpfs backed '/run' directory. also adds double stat'ing to make it possible to remove locks without certain race condition issues. this new mechanism is only employed when we can be sure, that a reboot has occured so that all processes are using the new locking mechanism. otherwise, two separate process could assume they have exclusive rights to a group or snapshot. bumps the rust version to 1.81 so we can use `std::fs::exists` without issue.
