libmount: Fix possible NULL dereference in get_btrfs_fs_root()

The function mnt_table_get_fs_root() should be robust enough to accept
NULL as mountinfo -- the right behaviour is to default to '/'.

The set_fs_root() (tab_update.c) has to understand when mountinfo is
necessary (for bind mounts and btrfs).
