Admin-client doesn't work on other architectures - aarch64, ppc64le, s390x

[im-konge]

As part of our build pipeline, we are building multi-arch images. The clients like (HTTP) producer, (HTTP) consumer, streams work fine, there is no issue regarding different architecture.
But for the admin-client, we are getting errors like:

exec /admin-client/admin-client: exec format error
command terminated with exit code 1

when used on different architecture than x86.
This issue have to be investigated and fixed.
