test_coverage: calculate the difference in reverse

Browse Source 
If we increase the coverage the message prints a negative value
as the difference from the previous value. This can be confusing
as it looks like the coverage has decreased.

For example if the value in coverage_config_x86_64.json is 73.42,
and the new coverage is 73.96 (increased), we have the following
error:

    ValueError: Current code coverage (73.96%) deviates by -0.54%
    from the previous code co...

Let's calculate the difference in reverse so that we have a
negative value if it decreases and positive otherwise.
