btrfs: test if rename handles dir item collision correctly
This is a regression test for the issue fixed by the kernel commit titled
"btrfs: correctly calculate item size used when item key collision happens"
In this case, we'll simply rename many forged filename that cause collision
under a directory to see if rename failed and filesystem is forced readonly.
