Look for snapshots in `/run/timeshift/backup/timeshift-btrfs` instead of `/run/timeshift/$PID/backup/timeshift-btrfs.` This is to be used for Timeshift versions <22.06.

This is a flag to activate the auto detection of the path where Timeshift stores snapshots. Newer versions (>=22.06) of Timeshift mount their snapshots to `/run/timeshift/$PID/backup/timeshift-btrfs`. Where `$PID` is the process ID of the currently running Timeshift session. The PID is changing every time Timeshift is opened. grub-btrfsd can automatically take care of the detection of the correct PID and directory if this flag is set.
