Pass cargolock/cargotoml via file instead of via env var

Browse source 
Apparently the cargolock env var can become too big so we replace it
with a file. This fixes the following error:

  building
  '/nix/store/s8bv90acizsyvh1s9gk7yvpiyw2gcpnx-dfinity-application-and-others-deps.drv'...
  while setting up the build environment: executing
  '/nix/store/cinw572b38aln37glr0zb8lxwrgaffl4-bash-4.4-p23/bin/bash':
  Argument list too long

See the following on the background of why env vars can become too big:
