Subject: OVMF: Convert from EmuVariableRuntimeDxe to VariableRuntimeDxe.

OVMF utilizes EmuVariableFvbRuntimeDxe to provide an emulated
variable firmware volume block device for non-volatile variables.
This allows the VariableRuntimeDxe and FaultTolerantWriteDxe
to function without a real non-volatile backing store.
