tests/qtest: Do not use versioned pc-q35-5.0 machine anymore

As of QEMU v10.2.0, the v5.0.0 machines are not usable anymore.

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

  $ qemu-system-x86_64 -M pc-q35-5.0
  qemu-system-x86_64: unsupported machine type: "pc-q35-5.0"
  Use -machine help to list supported machines

See commit a35f8577a0 ("include/hw: add macros for deprecation
& removal of versioned machines") and f59ee04406 ("include/hw/boards:
cope with dev/rc versions in deprecation checks") for explanation
on automatically removed versioned machines.
