python3Packages.cwcwidth: fix tests on darwin

use the same locale settings used by upstream's CI: https://github.com/sebastinas/cwcwidth/blob/2bc4360474b524148ffde3c8b837cbb0a4f172f5/.github/workflows/build.yaml#L33 this has the effect of skipping some otherwise-failing tests on darwin. seems slightly counterproductive but who am i to judge?
