efi: Actually add items to safemode menu.

The call to smp_... is not working since it relies on gKernelArgs being
fully initialized, which it isn't at this stage in the EFI loader. Jessica
says that in order to have that happen, the heap would also need to be
initialized early, which it also is not.

At least you can now force a safe videomode, which is enough for me to
be able to test video drivers.
