Commit d8fb7d0969d5c32b3d1b9e20b63ec6c0abe80be4 ("vl: switch -M parsing
to keyval") stopped adding the "machine" QemuOptsList. This causes
"machine" options to not show up in QMP query-command-line-options
output. For example, libvirt cannot detect that kernel_irqchip support
is available.
Adjust the "machine" opts enumeration in
qmp_query_command_line_options() so that options are properly reported.

Given that there's an "if" either way, I guess it's easiest to do it
this way. It may be even be possible (later) to build the info from the
MachineClass properties instead.
Queued, thanks!
