qemu-binfmt-conf.sh when it is used with systemd
needs to know for which CPU the systemd-binfmt.service
file must be created (i.e. "--systemd ppc").

But sometime, for instance for test purpose, we need to
create an entry for all known architectures.
This patch entroduce the "ALL" parameter for this purpose.
