Don't call QueryVariableInfo() on EFI 1.10 machines
The EFI 1.10 spec (and presumably earlier revisions as well) didn't have
RT->QueryVariableInfo(), and on Chris Murphy's MacBookPro8,2 , that
memory appears to be initialized randomly.
This patch changes it to not call RT->QueryVariableInfo() if the
EFI_RUNTIME_SERVICES table's major revision is less than two, and
assumes our maximum variable size is 1024 in that case.
