OvmfPkg: AcpiS3SaveDxe: don't fake LockBox protocol if SMM_REQUIRE 

In SVN r15306 (git commit d4ba06df), "OvmfPkg: S3 Resume: fake LockBox
protocol for BootScriptExecutorDxe", we installed a fake LockBox protocol
in OVMF's AcpiS3SaveDxe clone. While our other AcpiS3SaveDxe
customizations remain valid (or harmless), said change is invalid when
OVMF is built with -D SMM_REQUIRE and includes the real protocol provider,
"MdeModulePkg/Universal/LockBox/SmmLockBox/SmmLockBox.inf".
