* container_update_resources.go: it is Windows and Linux that need special handling
* local*.go: all platforms use the same list of tasks
* temp_unix.go/temp_unsupported.go: Darwin is a Unix
* util_unix.go/util_unsupported.go: use generic unix tag
The only user-visible effect of these changes is that tempMountLocation is now properly handled on Darwin
