elisp.eclass: Call makeinfo with --no-split option

By default, makeinfo will split output files larger than 300 kB into
smaller subfiles. Although this doesn't currently happen for any elisp
package, it might happen in future and could break some assumptions.
This is also consistent with GNU Emacs itself which installs unsplit
Info files for its documentation.
