EFI bootmgr works even without variables, since it scans for removable
paths as well.
I don't have strong opinions on this change. Duo is too resource
constrained for generic distributions, so it shouldn't be too surprising
not to have UEFI by default.
But if it's me, I'll be happy to keep it enabled if the storage (usually
SD-card here, and I don't think the BROM imposes a limitation) and
boot time allows.
