[PR] Use correct `make_` filters rather than old `ttfmake_`

At some point, Make changed all actions and filters to be prefixed with `make_` instead of `ttfmake_`. There is a back compat converter in the upstream theme that I'm guessing I missed in the sync to our build. Rather than trying to maintain backcompat, this adjusts the current `ttfmake_` filters to be `make_` filters and should resolve #145
