[PATCH] yank: Avoid linking into executables that don't want it

[Markus Armbruster]

util/yank.c and stubs/yank.c are both in libqemuutil.a, even though
their external symbols conflict.  The linker happens to pick the
former.  This links a bunch of unneeded code into the executables that
actually want the latter: qemu-io, qemu-img, qemu-nbd, and several
tests.  Amazingly, none of them fails to link.

To fix this, the non-stub yank.c from sourceset util_ss to sourceset
qmp_ss.  This requires moving it from util/ to monitor/.
