Commit Message

CP-312095: xenopsd/QEMU cross-version compatibility (#6992)

Newer versions of QEMU accept slightly difference arguments than older
versions.

- chroot and runas were replaced with run-with
- 'on'/'off' boolean values are accepted in most versions
- global variables are machine/device dependent

Adding global variables for both piix3-ide and piix3-ide-xen ensures the
variables are present the relevant device, variables which do not apply
to any devices in use will log a warning (in daemon.log) but are
otherwise ignored.

Example of the warning(s) produced:
```
<time> <host> qemu-dm-<domid>[<pid>]: qemu-dm-<domid>: warning: global piix3-ide-xen.subvendor_id has invalid class name
<time> <host> qemu-dm-<domid>[<pid>]: qemu-dm-<domid>: warning: global piix3-ide-xen.subsystem_id has invalid class name
```

These changes were tested alongside QEMU version 4.2.1 and QEMU version
10.1.0, in both cases guests booted as expected and the respective
warning appeared in the daemon log.
