tests: fix to pass with non-verbose libcurl build (#423)

Building libcurl with `CURL_DISABLE_VERBOSE_STRINGS` changes some stderr
outputs. Before this patch, this caused such build to fail 3 tests.

Fix and verify with these updates:
- test.py: support multiple accepted stderr result.
- tests.json: add alternate expected stderr results, as emitted by
  non-verbose libcurl.
- GHA/curl-for-win: add Linux job to actually test this issue.
  Oddly, Windows passes tests. This is due to a WINE workaround in
  `test.py` which replaces actual result with the expected one, masking
  failures.
