tests/data/acpi/rebuild-expected-aml.sh creates files for arm virt that don't exist in git

[Peter Maydell]

I'm doing a patchset that requires rebuilding the bios-tables-test
expected-data files for the arm virt board. The instructions in
bios-tables-test.c say that you should run rebuild-expected-aml.sh
to update the data files. But running that script generates a lot
of new data files that don't exist in git at all and are unrelated
to the change I'm making:

Does the script need fixing to not generate these files, or should
they exist in the git repo?

thanks
