Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
ytcc could not be built reproducibly.

This is because it ships different contents depending on whether
'nocheck' is specified or not. Specifically, the lack of a
PYBUILD_AFTER_TEST line that cleans up the .pytest-cache directory
after running the tests.

Patch attached.
