[pkg-go] Bug#1070727: reportbug: podman does not run wasm/wasi images because of missing crun-wasm - easy fix

[Eugen Stan]

Package: podman
Version: 4.9.4+ds1-1
Severity: important

Dear Maintainer,

I followed the guide to run wasm images on my system and it failed with 
errors.

I believe the issue is that podman looks for crun-wasm binary by default.
I failed to configure podman to use crun instead of crun-wasm.
I created a simbolic link named crun-wasm:

sudo ln -s /usr/bin/crun /usr/local/bin/crun-wasm

More details bellow to reproduce:

This is the guide I followed 
https://news.opensuse.org/2024/01/19/podman-wasm-
support/

I installed podman, crun and wasmedge packages.
Created a rust package and image with this Containerfile

FROM scratch
COPY target/wasm32-wasi/debug/hello.wasm /
CMD ["/hello.wasm"]

When I ran the image I got this error

podman run --rm hello-wasm
WARNING: image platform (wasi/wasm) does not match the expected platform
(linux/amd64)
Error: requested OCI runtime crun-wasm is not available: invalid argument

After creating the crun-wasm symbolic link I got it working:

podman run --platform wasi/wasm --rm hello-wasm
Hello, world din wasm!

It might be that this bu is fixed by patching crun but I believe the 
issue is
happening with podman.

Thanks,
Eugen
