[Ray Strode <halfline src gnome org>]

commit f0a58481c0fde5ac9688d591920378cb9a5a1b27

    glocalfile: Support marking fuse.sshfs filesystems as remote
    
    This requires checking the type of a filesystem using `/proc/mounts`
    rather than `statfs()`, since `statfs()` doesn’t give the subtype of the
    mount. So it only returns `fuse` rather than `fuse.sshfs`.
    
    This commit changes the output of `gio info -f ./path/to/local/sshfs/mount`
    from `filesystem::remote: FALSE` to `filesystem::remote: TRUE`.

    Fixes: #2726
