Translation related scripts have incorrect paths

[wgu-taylor-payne]

Currently the executables related with this package are declared like so in package.json:

  "bin": {
    "intl-imports.js": "tools/dist/cli/scripts/intl-imports.js",
    "openedx": "tools/dist/cli/openedx.js",
    "transifex-utils.js": "tools/dist/cli/scripts/transifex-utils.js"
  },

but both intl-imports and transifex-utils are declared in tools/dist/cli/. This means that when frontend-base is installed, only the openedx executable is available in node_modules/.bin, because npm can't find the executables for the other two.
