iotests: Tweak 221 sizing for different hole granularities

Browse Source 
For some particular configurations of ext4, sizing an image to 84
sectors + 1 byte causes test failures when the size of the hole is
rounded to a 4k alignment. Let's instead size things to 128 sectors +
1 byte, as the 64k boundary is more likely to work with various hole
granularities.
