EPUB writer: Add a meta element specify the cover.
Some EPUB e-readers, such as the Nook, require a meta element inside the
OPF metadata block to ensure the cover image is properly displayed.
When generating an EPUB using the `--epub-cover-image` option, this
patch adds the following meta element to the OPF metadata block in
`content.opf`:
<meta name="cover" content="cover-image" />
