efi_loader: don't set EFI_RT_SUPPORTED_UPDATE_CAPSULE

The EFI_RT_PROPERTIES_TABLE configuration table indicates which runtime
services are available at runtime.

Even if CONFIG_EFI_RUNTIME_UPDATE_CAPSULE=y, we neither support
UpdateCapsule() nor QueryCapsuleCapabilities() at runtime. Thus we should
not set the corresponding flags EFI_RT_SUPPORTED_UPDATE_CAPSULE and
EFI_RT_SUPPORTED_QUERY_CAPSULE_CAPABILITIES in RuntimeServicesSupported.
