OvmfPkg: PlatformPei: don't allocate fake lockbox if SMM_REQUIRE 

Since our fake LockBox must not be selected with -D SMM_REQUIRE (see the
previous patch), it makes sense to set aside memory for it only if -D
SMM_REQUIRE is absent. Modify InitializeRamRegions() accordingly.

This patch completes the -D SMM_REQUIRE-related tweaking of the special
OVMF memory areas.
