xmlto 0.0.26

The bottled xmlto is currently broken because the full cellar path of GNU
getopt gets hardcode presently (and GNU getopt saw a version bump recently, it
seems).

It was actually only after making the fix that I stumbled upon this update,
which is listed on this "new" (more appropriate) homepage.

Closes Homebrew/homebrew#36647.
