Create a gitmailmap(5) page similar to how .gitmodules and .gitignore have their own pages at gitmodules(5) and gitignore(5). Now instead of "check-mailmap", "blame" and "shortlog" documentation including the description of the format we link to one canonical place.

This makes things easier for readers, since in our manpage or web-based[1] output it's not clear that the "MAPPING AUTHORS" sections aren't subtly different, as opposed to just included.
