This is intended to fix a bug where DDM iOS builds were not working in
release mode and failing at runtime with an error like:
```
Failed to find snapshot at /private/var/containers/Bundle/Application/CA6AA16E-2C5E-4C1F-A650-E48AC9AC68BD/my_app.app/Frameworks/ios.framework/ios.assets/kernel_blob.bin:
Error Domain=NSCocoaErrorDomain Code=260 "The file “kernel_blob.bin” couldn’t be opened because there is no such file."

```
I think what was happening is the Google internal build infra was trying
to create a release mode app with no kernel_blob.bin etc, but it
actually contained a flutter.so built for debug mode which was expecting
to find kernel_blob.bin.
See internal bug b/419694561 for full context.
