perf tests: Add daemon 'lock' test 



Add a test for the perf daemon 'lock' command ensuring only one instance
of daemon can run over one base directory.

Committer testing:

  [root@five ~]# perf test -v daemon
  76: daemon operations                                               :
  --- start ---
  test child forked, pid 793255
  test daemon list
  test daemon reconfig
  test daemon stop
  test daemon signal
  signal 12 sent to session 'test [793506]'
  signal 12 sent to session 'test [793506]'
  test daemon ping
  test daemon lock
  test child finished with 0
  ---- end ----
  daemon operations: Ok
  [root@five ~]#
