iotests: Omit length/offset test in 040 and 041

As of a follow-up patch to this one, the length of a mirror block job
will no longer directly depend on the size of the block device;
therefore, drop these checks from this test. Instead, just check whether
the final offset equals the block job length.

As 041 uses the wait_until_completed function from iotests.py, the same
applies there as well which in turn affects tests 030, 055 and 056. On
the other hand, a block job's length does not have to be related to the
length of the image file in the first place, so that check was
questionable anyway.
