include/hw/vfio/vfio-container-base.h: rename file to vfio-container.h

With the rename of VFIOContainerBase to VFIOContainer, the vfio-container-base.h
header file containing the struct definition is misleading. Rename it from
vfio-container-base.h to vfio-container.h accordingly, fixing up the name
of the include guard at the same time.
