Subject: [PATCH] Add support for other podman runtimes

While the podman runtime is still enforced, the script now supports
several other runtimes. The KRUNVM_RUNNER_RUNTIME variable should
contain the word podman, followed by the plus sign, followed by the
runtime to use, e.g. podman+krun will pass the value of krun to the
--runtime option of podman create/run.
