[LTP] [PATCH V2 3/9] tracing/ftrace: add a new case for signal_generate

[Chunyu Hu]

From: Li Wang <liwang@redhat.com>

PURPOSE: check signal:signal_generate gives 2 more fields: grp res

This testcase is writing for signal events change:
       6c303d3 tracing: let trace_signal_generate() report more info...
       163566f tracing: send_sigqueue() needs trace_signal_generate() too
