farm: add --quiet/-q flag to podman farm list

[umar11b]

The command feature 'farm' is really helpful when it comes to building multi-architecture container images, with a build out on various different CPU architecture machines (e.g. amd64, arm64 etc.). With this we essentially produce a multi-architecture image useable on many different kinds of machines. Once those farms are built, we can list them out (ls) in a human readable format.

Essentially, when we do a 'podman farm list', it will print out every field (e.g. name, connections, default etc.). What --quiet & -q flags does is it cuts the noise by ONLY printing the names of the farms, rather than all the other farms list metadata.

Benefits of having this feature in the future is for automation and scripts to just pull the farm names from the list. This is mostly important for the CI pipelines to loop over.

Note: make validatepr fails at hack/ci/pr-removes-fixed-skips.t due to a missing Perl module (Test::Differences) in the validatepr container image; Unrelated to this change. All lint/format/docs steps (golangci-lint, pre-commit hooks, markdown-preprocess, xref-helpmsgs-manpages) passed clean.
