oe-time-dd-test.sh: increase timeout to 15 sec
With the previous timeout of 5 seconds, there would be
builds such as:
https://autobuilder.yocto.io/pub/non-release/
20210417-13/
which produced 17 files with top output with top running 454 times
and that's a bit too much data to analyze for each run. By
increasing the timeout, we'll find the worse problems
first, fix them and then we can decrease the timeout if needed.
