Offset and size should be aligned with cluster_size when inserting or
collapsing range on ext4 with 'bigalloc' enabled. Currently fsx only
align offset/size with block size.

In fact I have no idea which is the best way to fix this isue. On one hand,
fsx should be general and has no knowledge of the underlying filesystem.
Besides the cluster size seems to be stored on ext4_super_block and there's
no easy way to get it. But on the oter hand, quite many tests call fsx
directly, e.g., generic/127, rather than the generic routine run_fsx()
defined in common/rc.
