perf stat: Add missing newline in pr_err messages

The newline is missing for error messages in add_default_attributes()

Before:

  # perf stat --topdown
  Topdown requested but the topdown metric groups aren't present.
  (See perf list the metric groups have names like TopdownL1)#

After:

  # perf stat --topdown
  Topdown requested but the topdown metric groups aren't present.
  (See perf list the metric groups have names like TopdownL1)
  #

In addition, perf_stat_init_aggr_mode() and perf_stat_init_aggr_mode_file()
have the same problem, fixed by the way.
