tracing: Use double-dash spelling for trace option
The '-trace' and '--trace' spellings are only both supported in qemu binary, while for qemu-nbd or qemu-img only '--trace' spelling is supported. So for the consistency of trace option invocation, we should use double-dash spelling in our documentation. This's also mentioned in https://wiki.qemu.org/BiteSizedTasks#Consistent_option_usage_in_documentation .
