Export `copyrightMessage` from Text.Pandoc.App module.

Export `copyrightMessage` from the unexported module
Text.Pandoc.App.CommandLineOptions
and reexport from Text.Pandoc.App [API change].

This avoids the need for a duplicated version in pandoc-cli, which can
now depend on the library's exported version.
