[PATCH] perf test: Fix test case 120 and 121 for s390

[Thomas Richter <tmricht@linux.ibm.com>]

Perf tests
120: 'perf data convert --to-ctf' command test
121: 'perf data convert --to-json' command test
fail on s390. It is caused by selecting the default event cycles
which does not exist on s390 z/VM. Use software event cpu-clock
and specify it explicitly on the command line.

Output before:
❯ perf test 120 121
120: 'perf data convert --to-ctf' command test       : FAILED!
121: 'perf data convert --to-json' command test      : FAILED!

Output after:
❯ perf test 120 121
120: 'perf data convert --to-ctf' command test       : Ok
121: 'perf data convert --to-json' command test      : Ok
