MINOR: trace: implement source alias

Add a new "alias" member in trace_source structure. Its purpose is to be
an alternative to the member "name". This will be used in the next patch
to allow renaming of QUIC mux traces while preserving compatibility.

This new member is only used in trace_find_source() which is the helper
used to retrieve a trace source from its name.
