The runtime directory holds what the helpers we fork off need: swtpm's socket and, unless --tpm-state= points elsewhere, its state, the virtiofsd sockets, the varlink control socket, and the QEMU config file. runtime_dir was declared after the CLEANUP_ARRAY() that terminates those helpers, and cleanup handlers run in reverse declaration order, so the directory was removed while all of them were still running. That produces spurious errors from the helpers, and anything they create while rm_rf() walks the tree can make the final rmdir fail and leave the runtime directory behind. Declare runtime_dir before the CLEANUP_ARRAY() instead, so the helpers are sent SIGTERM and reaped first and the directory only goes away once nothing writes to it anymore. While at it, drop the rm_rf_physical_and_freep() destructors from the SSH key paths. They are only ever assigned paths below the runtime directory, whose removal takes them along, so those destructors never had an effect.
