perf tests: Add daemon 'signal' command test 



Add a test for the perf daemon 'signal' command. The test sends a signal
to configured sessions and verifies the perf data files were generated
accordingly.

  Committer testing:

  [root@five ~]# perf test daemon
  76: daemon operations                                               : Ok
  [root@five ~]# perf test -v daemon
  76: daemon operations                                               :
  --- start ---
  test child forked, pid 790017
  test daemon list
  test daemon reconfig
  test daemon stop
  test daemon signal
  signal 12 sent to session 'test [790268]'
  signal 12 sent to session 'test [790268]'
  test child finished with 0
  ---- end ----
  daemon operations: Ok
  [root@five ~]#
