qtwebengine: Limit buildtasks to save memory

The qtwebengine builds memory consumption is dependent on the number of ninja
tasks. This in turn depends on the PARALLEL_MAKE variable. In our build
environment with currently 24 cores it exhausts all the available memory.
Even worse on the CI machine that does bitbake jobs in parallel.

Try 8 jobs for now.
