Use 2 cores per job in github build

Browse Source 
As of today, https://docs.github.com/en/actions/reference/virtual-environments-for-github-hosted-runners
states that hosted runners have a 2-core CPU.

This uses make -j $physical_cores to try and be better about utilizing the time spent on those machines.
When github upgrades runners to have more cores we'll benefit from that too.
