Remove stray references to crash_service.

Stop bundling it in the installer (FILES.cfg). Remove the references
to the crash_service target from the perf builders' targets. (Issue
601762)

It's necessary to proceed with the removal of the start_crash_service
step on the bots, because putting it back now breaks the GPU bots
(Issue 601839).

The BUILD.gn removals are proactive, and not actually used yet.
