volumes: be more tolerant and fix infinite loop
Make Podman more tolerant when parsing image volumes during container
creation and further fix an infinite loop when checking them.
Consider `VOLUME ['/etc/foo', '/etc/bar']` in a Containerfile. While
it looks correct to the human eye, the single quotes are wrong and yield
the two volumes to be `[/etc/foo,` and `/etc/bar]` in Podman and Docker.
When running the container, it'll create a directory `bar]` in `/etc`
and a directory `[` in `/` with two subdirectories `etc/foo,`. This
behavior is surprising to me but how Docker behaves. We may improve on
that in the future. Note that the correct way to syntax for volumes in
a Containerfile is `VOLUME /A /B /C` or `VOLUME ["/A", "/B", "/C"]`;
single quotes are not supported.
This change restores this behavior without breaking container creation
or ending up in an infinite loop.
