Context: The `aesm_service` binary depends on a vendored library called `CppMicroServices`. At build time, this lib creates and then bundles service resources into a zip file and then embeds this zip into the binary. Without changes, the `aesm_service` will be different after every build because the embedded zip file contents have different modified times. All credits to @haraldh for this patch <3
