[IMP] requirements: resolve compatibility issues for 3.8 and 3.9

Only updates outdated requirements which actively cause issues:

* freezegun broken in 3.8 (removal of time.clock)
* xlrd broken in 3.8 (removal of time.clock)
* also monkeypatches xlrd.xlsx for 3.9 (removal of
  Element.getiterator, breaks because of defusedxml)
* jinja triggers DeprecationWarning in 3.8
* pillow triggers warning in 3.9
* lxml, greenlet don't compile in 3.9
* reportlab doesn't work in 3.9

New versions try to match those of Debian Bullseye.

Also adds a script to more easily compare dependency versions between
the requirements files and what's in various distributions (currently
supports checking against debian and ubuntu).

Furthermore updates warnings filtering:

* removes xlrd (mischeck was monkeypatched as noted above)
* removes setuptools (was for older versions, one would hope this
  isn't an issue anymore)
* adds babel: python-babel/babel#684 fixes the deprecation warning but
  is not part of any release yet
* ignores error related to `random.sample` on a set, this is a
  diagnostics bug because recordsets implement both Sequence and Set,
  and the stdlib checks for Set first (bpo-42470)
