Fix CheckHolePunch for bigger than 4k blocks.

With the new 64k ARM core, you can use filesystems with up to 64k block
size.
Currently Kudu does not start if the data is on a filesystem with larger
than 4k blocks.
Problem: CheckHolePunch has hard-coded 4k block size instead of using the
get env->GetBlockSize.
Kudu seems to be running fine on a 64k fs after this fix.
