Log:
  Mk/Uses/go.mk: Avoid pollution of Go module cache with modules downloaded by gomod-vendor
  
  Use module cache local to the WRKDIR and add the -modcacherw flag (available in
  go1.14 [1, 2]) to instruct go mod vendor to leave directories in the module
  cache read-write instead of making them unwritable.
