Increase timeout value for ppc64 sanitizer buildbots

[seurer]

Summary

We've been seeing some timeouts on sanitizer tests lately. I'd like to increase the timeout value to 1800 so that the runs can finish.

Hello Bill,

Did you have a chance to analyze the reasons of slow tests?
Slow slaves? Problem targets? Issues with the tests? Something else?

Thanks

The particular machines we are using right now are CPU starved because of multiple users including some other buildbots. As we get more hardware this should ease but in the meantime I'd like to get the bots to at least finish their runs.

LGTM

This worked and the Power big endian sanitizer now runs to completion. There is an issue open to fix the underlying performance problems (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63927) and when that is fixed this change can be probably be undone.
