Subject: [PATCH] perf stat: Add missing newline in pr_error 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.
