Commit 46cad549 ("WiP flake.nix: make docker image usable for...")
added 'root' to the swtpm_setup call, but broke skip-if-exist because
the flags are supposed to be comma-separated. swtpm_setup was ignoring
skip-if-exist and would fail if the config files exist.
Put a comma there so it works again.
