[PATCH v2 2/4] xfstests: btrfs/132: add test for invaild update time by an incremental send

Test that an incremental send operation dosen't' work because
it tries to update the time to a deleted directory after it finishes
a move operation.

The other one is that an operation is applied to a file using the old
name not the new name.

This test exercises scenarios used to fail in btrfs and are fixed by
the following patches for the linux kernel:

"Btrfs: incremental send, add generation check for the inode waiting for rmdir operation."
"Btrfs: incremental send, add generation check in existence demtermination for the parent directory"
