Workaround for uefi job with ubuntu bionic

In ubuntu bionic, the UEFI provided in the ovmf package version
0~20180205.c0d9813c-2, EFI v2.70 by EDK II, seems broken and
causes kernel panic.
To be able to boot using uefi, we download and install the old
working version 2.60 from the multiverse repository.
