flt.lttng-utils.debug-info: Don't copy trace class UUID to output trace class

A `flt.lttng-utils.debug-info` component creates an output trace class
that may be different that of the input trace class, so the UUID should
not be copied. In fact, we don't need a UUID at this point. the sink
component can decide to add one later.
