Use .jar files from the .NET runtime pack (#7665)

Since dotnet/runtime#77386 has been merged, .NET will require a certain class from  `libSystem.Security.Cryptography.Native.Android.jar` that will be located in the runtime pack files.

I'm not sure if this is the best way to pull the .jar from the runtimepack so feedback is welcome.

* Collect jar files from the runtime pack
* Remove invalid dependency
