Log:
  Mk/Uses/go.mk: Explicitly set modules-aware mode depending on "modules" argument
  
  Until now, go.mk relied on default Go behavior of switching to modules-aware
  mode only in the presence of go.mod and building in legacy ("GOPATH") mode
  otherwise. This changes with go1.16 [1] which flips defaults to always build in
  modules-aware mode and needs an explicit GO111MODULE=off to turn modules off.
  
  Stop relying on Go defaults and set build mode explicitly depending on
  "modules" argument in USES=go.
