pyoxidizer: fix building with PEP 517 support I'm not sure when this broke, because f6b045910d82 explicitly says it's fixing something, but a recent attempt to build pyoxidizer on Windows specifically flagged `--no-use-pep517` as a problem. Now that we have PEP 517 support for building, this goes away and pyoxidizer 0.17.0 with rust 1.54.0 works again (yeah, these should be updated). Note that `py -3.9 run-tests.py --pyoxidized` fails to get the version info on a zstd repo, and thus fails build and install hg to run the tests. A zlib repo works, and since there's a PR that changes obtaining the version info from `setuptools-scm`, I'm not bothering to fix this. With the zlib test run, the following are broken: Failed test-commit-interactive.t: output changed Failed test-i18n.t: output changed Failed test-log.t: The diffs all look to be related to not applying the requested i18n locale. IDR if this was the case when this was being tested 4 years ago (but I suspect it was not).
