Subject: [PATCH] ci: use at most the number of make threads as there are cores
 on mac and linux github runners (#2437)

We previously told make to run as many threads as it likes on these CI
jobs, but that might sometimes hit resource limits like RAM or the
allowed number of open files.

These numbers were found experimentally by using `sysctl -n hw.ncpu` on
mac and `nproc` on linux.
