parse: allow parsing anomaly non-human value for memory control group

[flouthoc]

Memory control group accepts an anomaly value of -1 for setting swap to unlimited.
Buildah must accepts this value if specified.

Reference: https://github.com/opencontainers/runtime-spec/blob/main/config-linux.md#memory

Closes: #3675

[flouthoc]

We use docker helpers to parse human readable value for swap which is ok for memory but swap also accepts exception of -1 which is not honored by the same helper. So PR handles that.

I think buildah static build is facing the same issue as: containers/crun#812

@cevich @edsantiago I suspect this a nixos/nix:latest regression any suggestions if we should do that same for buildah or not. Let me know if there is any better approach.

I'm totally fine with disabling nix, it seems to be a constant source of problems. I think this is how @cevich disabled it in podman:

diff --git a/.cirrus.yml b/.cirrus.yml

LGTM

That will simply ignore the results. I suggest just nuke the whole task (and remove it from success also).

Changes LGTM
@hswong3i any thoughts on the nix issue(s)?

@saschagrunert PTAL

[saschagrunert]

I'm not blocking on removing the static builds.
