[Qemu-devel] [PULL 1/2] docs: update the usage example of "dtrace" backend in tracing.txt

[Stefan Hajnoczi <stefanha@redhat.com>]

From: Lin Ma <lma@suse.com>

The usage example of dtrace is quite ancient, We have tracetool.py with
different parameters instead of the original tracetool shell script for
a long time, So update the old information.
