configure: check for pytest with python -m pytest

On different distro, pytest is suffixed with different patterns.

On the other hand, `python3-pytest' could be invoked correctly,
via `python3 -m pytest', the latter is used by our tests, now.

Switch to `$python -m pytest` to fix address all incompatible naming.
