Summary: rL364517 introduced further instances of `od` output checking of the kind previously corrected by rL363829. This patch corrects the issue by suppressing output of the input offset. The check remains sufficiently sensitive to test for the intended value of the specific byte since the relevant byte value is the only output we are expecting from `od`.

## In this test case we check that we can override the default values for

## e_shentsize, e_shoff, e_shnum and e_shstrndx fields in the YAML.
|
|
|
|
## First we check the default values.

# DEFAULT: Size of section headers: 64 (bytes)
|
|
# DEFAULT: Number of section headers: 4
|
|
# DEFAULT: Section header string table index: 3
