test/nvmf: Add interrupt mode testing for vfio-user 



Run nvmf with vfio-user in both polling mode and interrupt mode.

We are just testing some minimal vfio-user set up in interrupt mode,
but not actually testing any commands, since the vfio-user transport
used by lib/nvme code currently requires mapped device doorbells.
