tracing: Don't show dynamic string internals in synthetic event description
For synthetic event dynamic fields, the type contains "__data_loc",
which is basically an internal part of the type which is only meant to
be displayed in the format, not in the event description itself, which
is confusing to users since they can't use __data_loc on the
command-line to define an event field, which printing it would lead
them to believe.
So filter it out from the description, while leaving it in the type.
