trace: Put all trace.o into libqemuutil.a
Currently all trace.o are linked into qemu-system, qemu-img,
qemu-nbd, qemu-io etc., even the corresponding components
are not included.
Put all trace.o into libqemuutil.a that the linker would only pull in .o
files containing symbols that are actually referenced by the
program.
