[PATCH v2 2/7] tests/functional: set 'qemu_bin' as an object level field

["Daniel P. Berrangé" <berrange@redhat.com>]

The 'qemu_bin' field is currently set on the class, despite being
accessed as if it were an object instance field with 'self.qemu_bin'.

This is no obvious need to have it as a class field, so move it into
the object instance.
