help: Better handle builtins when docs aren't installed

Browse Source 
__fish_print_commands just prints the commands we have man pages for,
and help uses that to figure out whether it should link
a command or a section. If the docs aren't installed it won't find
anything.

At least check the builtins, because we document them and it's easy.

This probably needs to be added at build time - glob
doc_src/cmds/*.rst.
