Unable to build OVMF firmware due to missing Subhook dependency

[secretfader]

It seems the version of edk2 used by this project has a Git submodule that was unpublished:

Cloning into '/home/nicholas/git/amdsev/ovmf/UnitTestFrameworkPkg/Library/SubhookLib/subhook'... 
remote: Repository not found.
fatal: Authentication failed for 'https://github.com/Zeex/subhook.git/'
fatal: clone of 'https://github.com/Zeex/subhook.git' into submodule path '/home/nicholas/git/amdsev/ovmf/UnitTestFrameworkPkg/Library/SubhookLib/subhook' failed
Failed to clone 'UnitTestFrameworkPkg/Library/SubhookLib/subhook'. Retry scheduled

There is a mirror of Subhook located at https://github.com/tianocore/edk2-subhook, but the original repo, along with the Zeex's other repos, has been removed from GitHub and is no longer public.

note that this is fixed on EDK2 master since tianocore/edk2#6402 (which makes it use the mirror @secretfader referenced above)

Will this need a change in AMDSEV to make use of the new EDK2 master?
