test: set umask for tests

Trott · addaleax · commit be16cc9fd639 · 2019-01-14T16:50:47.000+01:00
#25213 proposes setting umask in the Python test runner to avoid spurious test failures when running from a shell with a restrictive umask. This is a good idea, but will only fix the issue for tests run with the Python runner. Set it in `common/index.js` as well so that it fixes it even when tests are run directly with a `node` binary, bypassing the Python test runner.
