We could create our own fork under the <https://github.com/tianocore>
organization.

It does not require much extra maintenance or monitoring, in my opinion.
We only need to advance our fork to the actual master HEAD when we
intend to advance our submodule reference in edk2 as well. As long as
the submodule reference in edk2 does not move, the actual master HEAD of
the cmocka project may very well be ahead of our fork (mirror), without
causing issues.

I don't know who or what the <https://github.com/neverware-mirrors>
organization is, and I'd prefer not fetching code from them automatically.

Thanks
Laszlo
