Clonezilla for XP-era PCs: 32-bit build picked by CPU

Current Clonezilla is amd64-only. The menu now checks the CPU with iPXE's
cpuid --ext 29 (long mode): 64-bit CPUs get the current release (through
Debian's shim under Secure Boot), 32-bit-only CPUs (Pentium 4 without
EM64T, Pentium M, early Atom) get Clonezilla 3.2.0-5 i686, the last
32-bit release, from clonezilla-i686/. Without a cpuid command the 32-bit
build is used, which also runs on 64-bit CPUs; UEFI always gets the
64-bit build. A 'Clonezilla Live 32-bit' item forces it.
prepare-boot-tools.sh downloads it, the playbook deploys it.
