my-env: Provide explicit store path for "rm".

If you do not provide any dependencies which don't propagate coreutils,
you'll get "rm: No such file or directory". Like for example by using
this:

nix-build -E '(import <nixpkgs> {}).myEnvFun {
    name = "mybrokentest";
    buildInputs = [];
}'

Thanks to "ewemoa" from the #nixos IRC channel for spotting this.

Revert "protobuf: Clean up and update to version 2.6.1."

This reverts commit 18b306b0414c13b5584c2325e9a01e065d715498. Protobuf
releases are generally not very backwards compatible and likely to
break lots of stuff. E.g.

  http://hydra.nixos.org/build/17535340
  http://hydra.nixos.org/build/17535640
  http://hydra.nixos.org/build/17536998

eid-viewer: associate with text/plain (MIME type of .eid files)

Far from ideal, but at least it now shows up in most GUIs.
