trace/simple: Fix unauthorized enable
st_set_trace_file() accidentally enables tracing. It's called
unconditionally during startup, which is why QEMU built with the
simple trace backend always writes a trace file "trace-$PID".
This has been broken for quite a while. I didn't track down the exact
commit.
Fix st_set_trace_file() to restore the state.
