perf probe: Move print logic into cmd_probe()

Showing actual trace event when adding perf events is only needed in
perf probe command.  But the add functionality itself can be used by
other places.  So move the printing code into the cmd_probe().

Also it combines the output if more than one event is added.

Before:
  $ sudo perf probe -a do_fork -a do_exit
  Added new event:
  probe:do_fork        (on do_fork)

  You can now use it in all perf tools, such as:

      perf record -e probe:do_fork -aR sleep 1

  Added new events:
  probe:do_exit        (on do_exit)
  probe:do_exit_1      (on do_exit)

  You can now use it in all perf tools, such as:

      perf record -e probe:do_exit_1 -aR sleep 1

After:
  $ sudo perf probe -a do_fork -a do_exit
  Added new events:
  probe:do_fork        (on do_fork)
  probe:do_exit        (on do_exit)
  probe:do_exit_1      (on do_exit)

  You can now use it in all perf tools, such as:

      perf record -e probe:do_exit_1 -aR sleep 1
