virtio-fs qualifies as a bootable device minimally under OVMF, but
currently the necessary "bootindex" property is missing (fw_cfg kernel
boot notwithstanding).
Add the property. For completeness, add it to the CCW device as well;
other virtio-ccw devices seem to have "bootindex" properties too.
Example OpenFirmware device path for the "vhost-user-fs-pci" device in the
"bootorder" fw_cfg file:

Currently we do not have boot support for virtiofs on s390x (ccw)
Not sure if it is better if we should add the property now or whenever
boot support is implemented.
As of today we do have bootindex for block and net. Maybe it is better
to defer bootindex for virtio-fs-ccw until we can boot from it? In
that way management software can detect if this is bootable or not?

Sure, I can drop the "vhost-user-fs-ccw.c hunk".
(I guess I could even lift the property itself (replacing the alias) to
"vhost-user-fs-pci.c", for now -- what's everyone's take on that?)

Keep it as is. This would simplify a later addition to ccw.
