Fix permissions of qemu-ARCH-static in debian-base and other images

**What this PR does / why we need it**: proper fix for the issue I found in #67215. Some machines (like apparently workstations at Google) have a restrictive umask, so the `qemu-ARCH-static` binaries were getting installed in images without world read/execute permissions, causing utilities like `apt-get` to fail.

There was also a duplicate download/install of these binaries for `debian-iptables`, which further confused the issue. I've since removed that duplicate installation.

Many thanks to @BenTheElder for asking the right question to get me to look at the permissions again.

I haven't pushed any images yet. After merge, I'll build/promote `debian-base:0.3.2`, then update everything to use it, then push some more images, write some more PRs, ...

**Release note**:
