build(workflow-js): generate QuickJS bindings on NetBSD

rquickjs ships no pre-generated bindings for NetBSD, so the advertised
build fails trying to include a nonexistent bindings file. Enable the
bindgen feature for the NetBSD target, mirroring the Android arm
directly above. The explanatory comment is corrected from the Android
copy it was pasted from.
