blockbook: fix go version

[1000101]

Motivation for this change

Number behavior in 1.14 has changed: golang/go#37308 and it currently breaks blockbook (prevents it from starting). Therefore, we need to use builder for go 1.13.

Moreover, I've added few parameters during build so the resulting application will have nicer UI (version+commit instead of unknown/unknown). I have left the buildtime unknown as it would render the package non-reproducible and the resulting binary file hash would change, too.

In addition, I've bumped the package.

Things done

• Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
• Built on platform(s)
  • NixOS
  • macOS
  • other Linux distributions
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Determined the impact on package closure size (by running nix path-info -S before and after)
• Ensured that relevant documentation is up to date
• Fits CONTRIBUTING.md.
