Package `io/ioutil` was deprecated in golang 1.16, preventing podman from building under Fedora 37. Fortunately, functionality identical replacements are provided by the packages `io` and `os`. Replace all usage of all `io/ioutil` symbols with appropriate substitutions according to the golang docs. Signed-off-by: Chris Evich <cevich@redhat.com>
