Correct electron package wrapGAppsHook usage

[worldofpeace]

Describe the bug
The electron package tries to wrap in buildCommand.
Because of this the wrapper is completely void of any entries in XDG_DATA_DIRS.
It needs to be rewritten in whatever fashion that the makeWrapper call happens in postFixup.

This is why riot-desktop has needed to be wrapped recently fe6addb, it's because electron isn't wrapped correctly itself. A change should be made to stable to revert this to riot-desktop, and to backport this fix instead.

Expression: https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/tools/electron/generic.nix#L59

buildInputs should also have glib for it's setup-hook https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/tools/electron/generic.nix#L37.
