Increase the waiting time in gnt-job cancel test
Increase the waiting time in gnt-job cancel test

The wait that is used for gnt-job cancel could cause flakiness if the
wait is small enough for the job not to get canceled. This patch
doubles the waiting time - more than that is unfortunately probably a
bug.
