fs: add FS_IOC_GETFSSYSFSPATH
Add a new ioctl for getting the sysfs name of a filesystem - the path
under /sys/fs.
This is going to let us standardize exporting data from sysfs across
filesystems, e.g. time stats.
The returned path will always be of the form "$FSTYP/$SYSFS_IDENTIFIER",
where the sysfs identifier may be a UUID (for bcachefs) or a device name
(xfs).
