perf test: Fix test case 83 ('perf stat CSV output linter') on s390

Perf test case 83: perf stat CSV output linter might fail
on s390.
The reason for this is the output of the command

 ./perf stat -x, -A -a --no-merge true

which depends on a .config file setting. When CONFIG_SCHED_TOPOLOGY
is set, the output of above perf command is

   CPU0,1.50,msec,cpu-clock,1502781,100.00,1.052,CPUs utilized

When CONFIG_SCHED_TOPOLOGY is *NOT* set the output of above perf
command is

   0.95,msec,cpu-clock,949800,100.00,1.060,CPUs utilized

Fix the test case to accept both output formats.

Output before:
 # perf test 83
 83: perf stat CSV output linter       : FAILED!
 #

Output after:
 # ./perf test 83
 83: perf stat CSV output linter       : Ok
 #
