chore: update to coverage (#1285)

Github action fails because the runner's minimum supported version 
for CMAKE is 3.5 whereas the minimum version mentioned in `librdkafka` is 3.2
This PR introduces a (hopefully temporary) change which fetches the 
crates and modifies the `CMakeLists.txt` of `librdkafka` before installation
