Namely, we need to allow subclassing something of an unknown type (in qom_fuse.py), and we need to allow missing imports (recorded against fuse itself) because mypy will be unable to import fusepy (even when installed) as it has no types nor type stubs available. Note: Until now, it was possible to run invocations like 'mypy qemu/' from ./python and have that work. However, these targeted suppressions require that you run 'mypy -p qemu/' instead. The correct, canonical invocation is recorded in ./python/tests/mypy.sh and all of the various CI invocations always use this correct form.
