Add Automatic-Module-Name to MANIFEST

[jodastephen]

The idea of this commit is to get a release 1.7.26 done with automatic module names for the four outward-facing modules. This allows the issues of service loader, module-info and so on to be sidestepped for now.

This PR is not intended to be merged onto the master branch. Instead, it is intended for there to be a new branch in slf4j starting at 1232e85 where this is the first commit on the branch. I can't get GitHub to do this automatically, so you'd need to create the branch in slf4j first, and I can then re-raise the PR against the new branch. Alternatively, you can cherry pick this commit onto the branch.

There is a case to add Automatic-Module-Name to the inward-facing (impl) jars, but I'm still working out what the best strategy for those is.

thanks

Thanks. Based on @jodastephen's comment, you need to create a new branch and then merge these changes into the new branch. If you create the new branch, I can help with sending a PR with the changes.
