build: Keep CNAME file when updating gh-pages branch

The CNAME file on the gh-pages branch is used to link the gh-pages
to the gitblit.com domain. So it needs to stay around when updating
the gh-pages branch with new documentation pages.
This is possible since Moxie 0.10.0 with a new `keep` sub-element.
