Improper parsing or tokenization of command string with krun handler

[jonner]

When using the krun runtime handler with podman, commands with special characters often fail due to an apparent bug in parsing. For example, the following command works fine:

$ podman run --rm alpine /bin/sh -c 'ls && sleep 30'
bin
dev
...

But the following command fails:

$ podman run --rm --annotation run.oci.handler=krun alpine /bin/sh -c 'ls && sleep 30'

Should it be moved to libkrun?
