UEFI boot: remove wrong entry from GRUB menu

[ghost]

Currently freepto support the UEFI boot.

The last 2 entries (freepto and freepto-failsafe), which are the most intuitive to be selected, are wrong and generate the following error:

These entries should be removed or fixed.

On debian an UEFI virtual environment can be simulated with qemu/kvm and ovfm (UEFI firmware for virtual machines)

$ sudo apt-get install ovfm
$ qemu-system-x86_64 -cpu kvm64 -enable-kvm -m 512 -bios /usr/share/ovmf/OVMF.fd freepto-v0.1.2-2.img

+1 for me on removing. We could also consider replacing the world "live", that lot of people think of as "non-persistent".
