The recently introduced -async-teardown commandline option was not
wired up properly and did not show up in the output of the QMP command
query-command-line-options. This means that libvirt will have no way to
discover whether the feature is supported.
This patch fixes the issue by correctly wiring up the commandline
option so that it appears in the output of query-command-line-options.
