restyle fallback module to match project style
Reduces lint errors from 36 to 33 (-8%). Line count from 1910 to 1476 (-23%). Another step in resolving issue #2902. This also fixes a stupid mistake from an earlier commit where I didn't realize that osx/config.h was meant to be included as a semi-static file in the repository.
