Print only one error message if a build fails

Browse source 
E.g. instead of

  error: --- BuildError ----------------------------------------------- nix
  builder for '/nix/store/03nk0a3n8h2948k4lqfgnnmym7knkcma-foo.drv' failed with exit code 1
  error: --- Error ---------------------------------------------------- nix
  build of '/nix/store/03nk0a3n8h2948k4lqfgnnmym7knkcma-foo.drv' failed

we now get

  error: --- Error ---------------------------------------------------- nix
  builder for '/nix/store/03nk0a3n8h2948k4lqfgnnmym7knkcma-foo.drv' failed with exit code 1
