testUpgradeInstanceWithOldDataFs: Extend default tic delay before timeout.

This tic call has a lot of activities to process. Checking test result
history over the last 2 months, the whole test runtime is mostly under
800s, but with a handful of spikes around 1600s, with one at 2300s. So
pick just slightly more than the worst over 2 months.
