Commit 7d17ae2acf (.flake8: fix check for 80/132 columns) introduced a
difference in how flake8 behaves between the automatic checks done in
the CI, where the maximum line length is 132, and the local checks,
where the maximum line length is 80.
The rationale at the time was that we recommend 80 char lines, but that
we accept 132 when it makes sense for readability.
However, this is very annoying when running flake8 locally, because of
two reasons:
1. human reviews on python scripts have not been as thorough as we did
expect; indeed, we've let a lot of long lines slip through; this
causes a lot of spurious failures that hide away the actual errors;
2. when hacking on a python script, the issues reported will not be
caused by the current changes, so the many reported failures
actually hide away the newly introduced issues.
Additionally, our 'make check-flake8' rule already enforces the 132-char
limit, and the issues reported are different than when manually running
flake8 on individual files.
Furthermore, the readability rationale for the 80-char limit is
definitely shattered by the mere rationale of allowing 132-char limit
for... readability...
We've arrived to a point where this separation is causing our checks
around flake8 to become mostly unusable and useless, as they do not
report meaningful issues, and people are no longer paying attention, and
this has caused actual issues to be introduced.
Finally, terminal emulators of today have long lifted the 80-char limit,
and are more than capable of displaying 132-char wide lines.
Switch back to using a 132-char limit.
This reverts commit 7d17ae2acf.

We recommend wrapping at 80 columns but we accept 132 columns when it
makes more readable.
When running flake8 locally, use maximum line length 80.
But when running in GitLab CI, keep the check-flake8 job failing only
for lines longer than 132.

This script comes from the kernel source, so ignore any code style
warnings for it in order to keep it as close as possible to the original
one, making synchronization between repos easier.
The option --exclude for flake8/pycodestyle is an absolute list and has
a default, so ideally the default values should be added too.
But the use cases for flake8 in the tree are:
- when developing a new script or changing an existing one, the
developer calls flake8 only on that script;
- in the GitLab job, a list of all Python files to be tested is created
and then passed to flake8.
None of these involve calling 'flake8' without parameters, so don't care
about adding the default value.
