Currently we use the `go` command to read GOARCH and use the value for
matching manifests.
This change allows:
1. Specifying the arch through `TARGETARCH`
2. Falling back to `dpkg` if `go` is not available
3. Falling back to `uname -m` if `dpkg` is not available
4. A default value (amd64) if none of these commands is available.

The pattern `echo str | grep -qE pattern` likes to fail on the z CI here for
an unknown reason. Use `grep -qE pattern <<< str` instead.

Currently we only support 'application/vnd.docker.distribution.manifest.v2+json'
manifest images download, with more multi-arch images used, we need to support
download images with 'application/vnd.docker.distribution.manifest.list.v2+json'
format(aka "fat manifest"), else we will fail to download those multi-arch ones.
This PR adds 'application/vnd.docker.distribution.manifest.list.v2+json' manifest
support, thus we can download both multi-arch and legacy images.

When using a https proxy, an extra HTTP 200 header will be generated.
So we can't rely on detecting the first http header.
$curlHeaders with https proxy:
"HTTP/1.0 200 Connection established <-- the https proxy's response
HTTP/1.1 307 Temporary Redirect
...
"

If the registry responds directly with blob contents, use them,
otherwise follow the redirect without Authorization headers (which
likely aren't valid for the server being redirected to).
This preserves the basic structure of the previous output with up to one
additional progress bar per-layer (for the redirect request and then the
following blob request).

This is especially important for distributions like NixOS where `/bin/bash` doesn't exist, or for MacOS users who've installed a newer version of Bash than the one that comes with their OS.
