python3: Quickfix for Homebrew/homebrew#15943 & Homebrew/homebrew#16320.

- This is a temporary fix which removes the
  "Headers", "Python" and "Resources" symlinks
  from the `Python.framework`, such that both,
  python and python3 can be linked at the same
  time.

Closes Homebrew/homebrew#16367.
Fixes Homebrew/homebrew#16320.
