image_types: Correctness fixes

* Add a newline to improve the output formatting
* Use set() to turn the list into a set of unique items to prevnt
  the same image code running twice (for e.g. IMAGE_FSTYPES = "tar.gz tar.bz2")
* Support multiple compression extensions such as ".gz.u-boot"
* Fix basetype/type typo and fix multiple image generation
