Summary:
The publish script will fail on forked PRs anyway as the $CIRCLE_NPM_TOKEN envvar will be missing or incorrect.
We also move buck fetches to their own own shell script. These are shared by the Android and Deploy jobs, and using -ex will allow us to see which specific command failed without the need to list all steps in the config file.
Finally, cache keys are updated as architecture is only relevant in caches that may be reused across macOS and linux, which is not the case for Android.
