coverage.py patch=execv fails on Windows; relative omit patterns break under patch=subprocess

coverage.py 7.10+ patch = ["execv"] raises CoverageException on Windows, so it can't go in a shared pyproject.toml. Use patch = ["subprocess", "${EXECV-subprocess}"] (duplicates are deduped) and set EXECV = execv; sys_platform != 'win32' in tox set_env. Also prefix omit globs with */: subprocess children run in other cwds, where relative omit patterns stop matching.
