Recent signing attempts on branches that are building a limited set of
Apple platforms are failing:
Target "_UnzipNestedZips: (TargetId:3)" in file
"D:\a\_work\_temp\artifact-signing\extracted\SignList.targets" from
project "D:\a\_work\_temp\artifact-signing\SignFiles.proj" (target
"_CalculateItemsToSign" depends on it):

Error MSB4044: The "Unzip" task was not given a value for the required

We should only attempt to extract and sign content in `Broker.zip`,
`Build.zip`, and `Xamarin.PreBuilt.iOS.app.zip` if the zip exists.
