qemu-options.hx: 9p: clarify -virtfs vs. -fsdev
The docs are ambiguous about the difference (or actually their
equality) between options '-virtfs' vs. '-fsdev'. So clarify that
'-virtfs' is actually just a convenience shortcut for its
generalized form '-fsdev' in conjunction with '-device virtio-9p-pci'.
And as we're at it, also be a bit more descriptive what 9pfs is
actually used for.
