re-enable "Linux packages_autoroller" (#130088)

Fixes https://github.com/flutter/flutter/issues/129744

This change:

1. re-enables the Linux packages_autoroller
2. ensures we redact the token from appearing in any logs (in local testing I realized some failure logs might still expose the token)

What actually fixed authentication however was creating and uploading a new GitHub personal access token, not this change.

It's currently failing post-submit because being marked `bringup` it is running in the try pool, which does not have permissions to access the cloud KMS. However, I ran a LED build in the prod pool that succeeded:
