solana-validator: adapt update script to new nix-prefetch-github
The update script is also already broken and needs:

1. Add missing packages to the shebang.
2. Retrieve cargo hash from the proper package.

We also take the opportunity to switch ot using the newer "hash" and
"cargoHash" properties.
