Adjust WA iOS audit scripts to ensure dummy mobileconfig deps don't trigger them

Summary:
The MobileConfig codegen system on FoA is leverages a dummy_deps library (https://fburl.com/code/mpi4mhgl) in order to detect which mobileconfig params are defined on the dep targets.

This library introduces no sources and only replicates deps already in the build, as a result it doesn't affect the build in any meaningful way.

However, the dep verification signals on WA iOS are being triggered due to this new dep being introduced. This diff filters the problematic dep out of the workflows.
