generic/273: Remove hard coded block size

Browse Source 
The space occupied by files in the 'origin' directory is calculated with
the assumption that 4k is the block size of the underlying filesystem.
This causes the test to fail with ENOSPC errors when running on
filesystems with larger block sizes. To fix the issue, this commit makes
use of the the block size obtained from the mounted filesystem.
