ci: ignore parse errors from gcovr

The documentation for gcovr suggests this as a work around to a bug in gcovr
that cause negative hit values, which is impossible, and is not accepted by
default and will cause the CI to fail:
  -  https://gcovr.com/en/stable/guide/gcov_parser.html

To correct this, add option:
  -gcov-ignore-parse-errors=negative_hits.warn_once_per_file
