Subject: mkefidisk: Create interactive menu for the script

If it is passed only the image parameter, it will show some interactive
options to help to conclude the script.

With this patch it will detect devices available in the machine, asking
to choose what it is wanted to be flashed.

it will suggest the target device. If it is a SD card the suggestion
is /dev/mmcblk0. If it is a pendrive it will suggest to use /dev/sda.
