graphics/povray38: Remove NATIVE option and do some cleanups

- Drop NATIVE option, utilize CPUTYPE instead which is supported using
  the framework via /etc/make.conf
- Don't override optimization set by framework
- Utilize framework helpers more and do some slight rearrangement
  for better readability and consistency with Porters Handbook
