Because fusepy does not have type hints, add some targeted warning
suppressions.
NOTE: Prior to this change, running 'mypy qemu' from the python
directory worked OK, but only coincidentally. Going forward, you will
need to run 'mypy -p qemu' instead. These invocation forms will be
codified in a CI test soon.
