IncludeNativeLibrariesForSelfExtract not working with newer libsodium binaries for osx/linux-musl #45903

Describe the bug

As discussed here, publishing a single-file application for osx-x64/osx-arm64 with -p:IncludeNativeLibrariesForSelfExtract=true doesn't embed libsodium.dylib in the executable as of v1.0.19.1+ of the libsodium NuGet package. The same issue occurs with libsodium.a for linux-musl-x64/linux-musl-arm64. This wasn't a problem with v1.0.19. win-x64, win-x86, win-arm64, linux-x64, linux-arm64, and linux-arm don't seem to be affected.

As it's unclear why this is happening, I'm opening an issue here to try and get some help from .NET maintainers.

To reproduce

1. Download the latest .NET 8 SDK installer.
2. Create a folder to house the project and navigate to it in the terminal.
3. Create a new console project with dotnet new console --framework net8.0.
4. Install the libsodium NuGet package with dotnet add package libsodium --version 1.0.19.1.
5. Do a self-contained, single-file publish for macOS with dotnet publish -c Release -r osx-x64 -p:PublishSingleFile=true -p:PublishTrimmed=true -p:PublishReadyToRun=true -p:IncludeNativeLibrariesForSelfExtract=true --self-contained true. The extra options are just what I normally use.
6. Navigate to the printed path (bin\Release\net8.0\osx-x64\publish\), and you'll see there's a libsodium.dylib file.
7. Delete the files in this folder and return to the original project directory.
8. Change the libsodium package version with dotnet add package libsodium --version 1.0.19.
9. Use dotnet publish again as before.
10. Navigate to the printed path again, and you'll see there's no libsodium.dylib file. This is what you want.
