[PATCH 4/4] uefirtvariable: add stress test for UEFI runtime interface SetVariable with different name and data

[Ivan Hu]

This stress test tests the UEFI runtime interface SetVariable by
calling with different name and data multiple times.

This combine test do a lot of setvariable, reduce variablenamelength
and multitesttime, for saving the setvariable times to avoid running
out of nvram space and getting the EFI_OUT_OF_RESOURCES.
