Add nil check to privacy manifest generation

[swrobel]

Summary:

After upgrading my app from React Native 0.74.0 to 0.74.1, iOS builds were failing due to the privacy manifest ruby script failing due to what seemed to be a missing nil check.

[Privacy Manifest Aggregation] Appending aggregated reasons to existing PrivacyInfo.xcprivacy file.
[Privacy Manifest Aggregation] Reading .xcprivacy files to aggregate all used Required Reason APIs.
[!] An error occurred while processing the post-install hook of the Podfile.

no implicit conversion of nil into Array

Adding some good old puts debugging to this file indicated that the problem was that an invalid manifest file was being generated for react-native-image-crop-picker, which I don't understand, because it doesn't currently have a Privacy Manifest.

It seems there may be some upstream issue in whatever tool generates these missing privacy manifests, but that seemed beyond the scope of a simple nil check.
