sgx-sdk: disable mtime in bundled zip file for reproducible builds

Browse Source 
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.
