[PATCH] RFC: efi: Attempt to support automatically running SCT

[Simon Glass]

This is a feeble attempt to update the qemu script to run a selection of
UEFI tests. It copies a .seq file into the disk so it can be read by
SCT.

It doesn't seem to work and I am not sure why. I am posting it in case
someone else has ideas or wants to pic it up.

Once Ilias' CI solution is in place, I can perhaps come back to this.
