So take your epub, open it is Sigil (and yes your iTunesArtWork file goes away). Use Sigil's BookBowser to get a list of all images files in the epub. One of them must be the original epub's cover. Just identify which one it is by opening each one by double-clicking onit in BookBrowser. Then properly set the metadata in the opf so that Books and every other reader can find that file and determine it is the cover image.

When you add this edited epub to Books with the proper pieces in place, it will copy the indicated cover.jpg file and create a new iTunesArtwork file.

These iTunes extra pieces are just caches (copies) and extracts stored inside the epub zip archive of things that were already there in the epub from the very beginning. They do this for speed reasons once, so they do not have to search for these pieces again and again.
