build: make build-addons errors fail the build

The `build-addons` makefile target runs `tools/doc/addon-verify.js` and
then uses `touch` to update a timestamp file. Unconditionally calling
`touch` was losing the exit code from `tools/doc/addon-verify.js` so
any errors produced by that script were not failing the build.
