configs.py: Allow to override --jobs param for build system

Different CI jobs have different needs for parallelization. While normally
we build multiple configs in parallel (and so need to limit --jobs value),
for ECLAIR MISRA testing we may need to build configs sequentially, but
then parallelize each build using higher --jobs.
