The Ubuntu image for armv7 is over 1G, so make a smaller image for emulation.

It is slow, but it boots.

Welcome to Alpine Linux 3.18
Kernel 6.1.34-3-virt on an armv7l (/dev/ttyAMA0)

Not every dependency, such as nerdctl-full, is available for arm-v7. But most are...

ARCH_ALIAS doesn't seem to be used by build.sh anymore:

I think we can drop setting legacyBIOS: true for all platforms now; it is no longer needed and has already been removed from the examples/alpine.yaml template in the lima.git repo.

Why do we set ARCH here at all? It isn't being used anymore at all. It seems to be vestigial code from the time when this block ended with:

    mkdir -p "${tmp}/usr/libexec/cni"
    ln -s "flannel-${ARCH}" "${tmp}/usr/libexec/cni/flannel"

But that has since been removed because the cni-plugin-flannel package has since been fixed. So we can drop all the ARCH setting here.
