proposed fix for #2588

as title says

an exfat partition here is auto-mounted now, and I also can mount/umount it by udevil or "mount"

TODO: test hfs+ (I can not test here) and ntfs3g-fuse (I believe ntfs was affected too)
TODO: check if network mounts are fine with util-linux

fuse-exfat bump is not important but nice-to-have

as a side note I would say that fuse-exfat is very unstable to me. mount.exfat crashes often here resulting in "Transport endpoint is not connected" errors. IMO using this fs should be discouraged or not even supported.
