OSS-Fuzz builds have been failing due to some strange issues that seem

Disable tcg to disable libffi.

IIUC we are using the QTest 'software [un]accelerator' to fuzz via I/O,
right?
Then maybe we can disable all accelerators to speed up build. But please
mention it in the commit description.
That would be nice, but needs some changes to meson.build, which doesn't
treat qtest as a real accelerator and will complain if building w/o tcg
and kvm:
error('No accelerator available for target @0@'.format(target))
We need to start with the binary using '-accel qtest', not "pick any
available accelerator randomly".
