[libvirt] [PATCH 02/12] qemu: caps: Tweak arm conditional in SupportsChardev

Rather than try to whitelist all device configs that can't use -chardev, blacklist the only one that really can't, which is the default serial/console target type=isa case. ISA specifically isn't a valid config for arm/aarch64, but we've always implicitly treated it to mean 'default platform device'.
