Hard-coded Code Climate test reporter ID

Apparently, there's no easy way to submit coverage reports from GitHub pull request builds
without exposing this reporter ID. Coverage diff reports should now come in from pull
request builds after this commit. The expectation is that Code Climate will comment on the
pull requests and mark the build as failed or succeeded based on the coverage diff.

This commit also disables sending code coverage reports to Codecov, which has been broken
for a while now: https://github.com/codecov/codecov-action/issues/43
