Ricardo Pardini 6755e9190a don't ship qemu binary in rootfs cache + armhf image/rootfs building on non-armhf-capable-arm64 hosts (Apple M1+) ...

- refactor `prepare_host_binfmt_qemu()` out of `prepare_host_noninteractive()` and into `rootfs/qemu-static.sh`
  - further split into more functions and return early to avoid deep nesting
  - implement force import and load of qemu-arm for non-armhf capable arm64 hosts (incl magic numbers)
- enhance `deploy_qemu_binary_to_chroot()` & `undeploy_qemu_binary_from_chroot()`;
  - add 2nd param "caller" for better logging/tracking
  - does sanity-check and preserve existing binary if it exists
- explicitly deploy/undeploy for the 3 cases:
  - image: moved undeploy from `post_debootstrap_tweaks()` into image build proper for consistency
  - rootfs: was leaving trash behind (since post_debootstrap_tweaks never ran for rootfs), now properly undeploys
  - initrd: was already fine, just added caller info
- added `arch-test` host dependency
  - ensure `arch-test ${ARCH}` works during prepare-host
- > tl,dr: "can build 32-bit armv7 armhf using Apple silicon; can use rootfs cache cross-arch reliably"
