Makefile: workaround for running dual containers with podman

When running the new test-multi-container make rule, I found that
podman generated "random" hex based hostnames for the containers.
These names work internally and do resolve but I found that putting
these in the ceph config files does not work as ceph sees them as
addresses, not hostnames, presumably due to the hex.
This change simply specifies the hostnames manually on the cli
so that both podman and docker should match docker's default behavior.
