runtime: use actual booleans for QMP device_add boolean options

Since
be93fd5372,
which is included in QEMU since version 9.2.0, the options for the
`device_add` QMP command need to be typed correctly.

This makes it so that instead of `"on"`, the value is set to `true`,
matching QEMU's expectations.

This has been tested on QEMU 9.2.0 and QEMU 9.1.2, so before and after
the change.

The compatibility with incorrectly typed options  for the `device_add`
command is deprecated since version 6.2.0 [^1].
