Wolfgang Walther 63301f9889 .github/workflows: set timeouts
None of our jobs is expected to run for 6 hours, the GitHub limit. These
limits are generous and take into accounts that some jobs need to wait
for others.

If jobs exceed these times, most likely something else is wrong and
needs investigation.
