As of QEMU v11.1.0, the v5.2.0 machines are not usable anymore.

Use the latest x86 q35 machine instead, otherwise we get:

   $ qemu-system-x86_64 -M pc-q35-5.2
   qemu-system-x86_64: unsupported machine type: "pc-q35-5.2"
   Use -machine help to list supported machines

See commit a35f8577a07 ("include/hw: add macros for deprecation
& removal of versioned machines") and f59ee044067 ("include/hw/boards:
cope with dev/rc versions in deprecation checks") for explanation
on automatically removed versioned machines.

I wonder whether we should rather remove the test completely instead? Those tests based on the fuzzers rely on a certain way of doing their MMIO - if a newer machine type has a slightly different MMIO layout, the test basically does not test anything useful anymore. WDYT?
