These were added back in commit c4935f30490d0446e16a51dbf7a6397b771cf804 because the tests required CPython 3.8, which was quite new at the time. But CPython 3.8 was released over 4 years ago (October 2019) and the CI test runners, and developers, have this (or a more recent) CPython version. Removing the .exp files also helps keep MicroPython semantics the same as CPython. The asyncio_fair.py test it adjusted slightly to have more deterministic timing and output.
