btrfs-progs: dump-tree: skip tree-checker when dumpping tree blocks

Since commit c8593f6 ("btrfs-progs: sync tree-checker.[ch] from
kernel"), btrfs-progs can do the kernel level tree block checks, which
is not really sutiable for dump-tree.

Under a lot of cases, we're using dump-tree tool to debug to collect the
details from end users.
If it's a bitflip causing a rejection, we would be unable to determine
the cause.

So this patch would add OPEN_CTREE_SKIP_LEAF_ITEM_CHECKS for dump-tree.
