Subject: DuetPkg: Fix build break caused by EFI_SPECIFICATION_VERSION usage

The EFI_SPECIFICATION_VERSION MACRO is no longer defined in edk2
builds, and this module does not need to support the older < UEFI 2.0
code path.

git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@10096 6f19259b-4bc3-4df7-8a09-765794883524
