scripts/cpu-x86-uarch-abi.py: Fix parameter error of cmd

When run this script, there's the error:

python3 scripts/cpu-x86-uarch-abi.py /tmp/qmp
Traceback (most recent call last):
  File "/path-to-qemu/qemu/scripts/cpu-x86-uarch-abi.py", line 96, in <module>
    cpu = shell.cmd("query-cpu-model-expansion",
TypeError: QEMUMonitorProtocol.cmd() takes 2 positional arguments but 3 were given

Commit 7f521b0 ("scripts/cpu-x86-uarch-abi.py: use .command()
instead of .cmd()") converts the the original .cmd() to .command()
(which was later renamed to "cmd" to replace the original one).

But the new .cmd() only accepts typing.Mapping as the parameter instead
of typing.Dict (see _qmp.execute()).

Change the paremeters of "query-cpu-model-expansion" to typing.Mapping
format to fix this error.

Fixes: 7f521b0 ("scripts/cpu-x86-uarch-abi.py: use .command() instead of .cmd()")
