Revert "Add a function to write mimetype"

This reverts commit 6aad662ec59a3974cbca6c423c1e08e8bc5e90f6.

There is no need to write it out to epub_root as it needs to be manually
written to the zip file later on anyway. Not including it saves us the
trouble of avoiding it when walking epub_root later.
