 Fix fragile T9579 tests

 Fix fragile tests according to comment 13 of #9579 (by @bherzog)

 Done by capturing stderr and replace `xx bytes` with `NUM bytes`
 (literal).

 Some numbers like `(1 MB)` would still remain, but I think
 it's safe to assume the actual difference in bytes (on different
 architectures) is too small to have an effect on the rounded megabyte
 value.

 Test Plan: validate
