iotests/297: Rewrite in Python and extend reach

Instead of checking iotests.py only, check all Python files in the
qemu-iotests/ directory. Of course, most of them do not pass, so there
is an extensive skip list for now. (The only files that do pass are
209, 254, 283, and iotests.py.)

(Alternatively, we could have the opposite, i.e. an explicit list of
files that we do want to check, but I think it is better to check files
by default.)

Unless started in debug mode (./check -d), the output has no information
on which files are tested, so we will not have a problem e.g. with
backports, where some files may be missing when compared to upstream.

Besides the technical rewrite, some more things are changed:

- For the pylint invocation, PYTHONPATH is adjusted. This mirrors
setting MYPYPATH for mypy.

- Also, MYPYPATH is now derived from PYTHONPATH, so that we include
paths set by the environment. Maybe at some point we want to let the
check script add '../../python/' to PYTHONPATH so that iotests.py does
not need to do that.

- Passing --notes=FIXME,XXX to pylint suppresses warnings for TODO
comments. TODO is fine, we do not need 297 to complain about such
comments.

- The "Success" line from mypy's output is suppressed, because (A) it
does not add useful information, and (B) it would leak information
about the files having been tested to the reference output, which we
decidedly do not want.

iotests: Run pylint and mypy in a testcase

We made sure that iotests.py passes pylint. It would be a shame if we
allowed new patches in that break this again, so let's just add a
meta-test case that runs pylint on it.

While we don't pass mypy --strict yet, we can already run it with a few
options that would be part of --strict to make sure that we won't
regress on these aspects at least until we can enable the full thing.
