mxnet: 1.1.0 -> 1.2.1

[danieldk]

Update and fix the build:

• Perl is a build-time requirement.
• Fix hardcoded /bin/bash invocation.

Motivation for this change

Build fails in 18.09, ZHF #45960.

(I plan to look at the Python mxnet module afterwards.)

Things done

• Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
• 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 nox --run "nox-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)
• Fits CONTRIBUTING.md.

a) For `nixos-rebuild` you can set
  { nixpkgs.config.allowUnsupportedSystem = true; }
in configuration.nix to override this.

b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
  { allowUnsupportedSystem = true; }
to ~/.config/nixpkgs/config.nix.

aarch64 failure is in a dependency, can be ignored for this PR.

mxnet builds, so this PR is good to merge.
