Inconsistently gftools-gen-stat and "compress" swap position in the build order

A client running one of my builder scripts has been encountering an inconsistent issue where the "gftools-gen-stat" command and "compress" commands switch places in the build order. This causes a fail as the variable font has not been saved to the output location before builder tries to compress it to a webfont.

build.ninja:
