gnu: python-aiohttp: Update to 3.7.3.

* gnu/packages/patches/python-aiohttp-3.6.2-no-warning-fail.patch: Delete file.
* gnu/local.mk (dist_patch_DATA): Adjust accordingly.
* gnu/packages/python-web.scm (python-aiohttp)[source](patches): Remove.
[arguments]: Use UTIME instead of calling out to 'touch'.  Don't delete
now-working tests; but disable some new ones.  Replace the 'check' phase.
[propagated-inputs]: Add PYTHON-TYPING-EXTENSIONS.
[native-inputs]: Remove PYTHON-PYTEST-RUNNER, PYTHON-PYTEST-XDIST,
PYTHON-PYTEST-TIMEOUT, and PYTHON-PYTEST-FORKED.  Add PYTHON-PYTEST and
PYTHON-RE-ASSERT.
