### Why I did it
Improve visibility for telemetry crashes by allowing core to be dumped.
### How I did it
Export GOTRACEBACK=crash as an environment variable.
#### How to verify it
Manual test
1) Change telemetry binary to crash always, first line of telemetry.go main() -> panic("problem")
2) Add change to telemetry.sh
3) Restart telemetry
4) See core in /var/core
