Pack keys in deb

[deepthiskumar]

The key file naming convention changed and wasn't updated in rebuild-deb.sh causing the deb to not have any keys at all. This is probably why daemon (when run from the installed deb) gets stuck for a long time when it is run the first time. (Will confirm this once build is completed)
Checklist:

  • Mention expected invariants, implicit constraints
• Tests were added for the new behavior
  • Document test purpose, significance of failures
  • Test names should reflect their purpose
• All tests pass (CI will check this if you didn't)
• Serialized types are in stable-versioned modules
• Does this close issues? List them:

Looks great and that explains a lot

Tested the deb with keys. It doesn't download the keys and therefore doesn't take too long during initialization now. It still takes ~1 min on my machine after this log Setting current protocol version to "0.1.0" from compile-time config before the prover and verifier processes are created. Probably the time to load 4.2 gb keys?
