vfio: Enable sparse mmap capability
The sparse mmap capability in a vfio region info allows vfio to tell
us which sub-areas of a region may be mmap'd. Thus rather than
assuming a single mmap covers the entire region and later frobbing it
ourselves for things like the PCI MSI-X vector table, we can read that
directly from vfio.
