Subject: [edk2-platform][PATCH v1 1/2] Platforms/RaspberryPi: Fix RPi4 RngLib build error

Commit b5701a4c7a0fb185e0c5b9db9525939c78664bfd introduced RngLib
dependency for OpensslLib, and caused the RPi build to break for lack
of an RngLib instance.

This patch adds RngLib using the DxeRngLib flavor, which is a wrapper
around the the EFI_RNG_PROTOCOL that the platform already produces.

Tested booting OSes and running the SCT test for EFI_RNG_PROTOCOL.
