run-tests: obtain code coverage via Python API
Before, we were invoking the "coverage" program provided by the
"coverage" module. This patch changes the code to go through the
Python API. This makes the next patch a little bit easier to reason
about.
A side effect of this patch is that writing code coverage reports
will be slightly faster, as we won't have to redundantly load
coverage data.
