I don't think it's causing any issues currently since it's not causing
undefined reference errors upstream. users of libqemuutil that make use
of qemu-sockets seem to be pulling qapi-types/qapi-visit in through other
dependencies.

I only noticed it because I was attempting to generate the native list
code via tests/Makefile and running into redefinition conflicts with
qapi-types.o/qapi-visit.o, then noticed the qemu-sockets.o issue when I
attempted to remove the qapi-types/qapi-visit dependency from
tests/test-visitor-serialization

Now that we're generating the native list code from top-level Makefile,
it actually doesn't seem to be needed by this series anymore, so maybe
I'll pull it out for now. I think a better fix would be to have
qapi/Makefile.obj add these to $util-obj-y directly anyway.
