Thomas Richter 463538a383 perf tests: Fix test 68 zstd compression for s390 
Commit 5aa98879ef ("s390/cpum_sf: prohibit callchain data collection")
prohibits call graph sampling for hardware events on s390. The
information recorded is out of context and does not match.

On s390 this commit now breaks test case 68 Zstd perf.data
compression/decompression.

Therefore omit call graph sampling on s390 in this test.

Output before:
  [root@t35lp46 perf]# ./perf test -Fv 68
  68: Zstd perf.data compression/decompression              :
  --- start ---
  Collecting compressed record file:
  Error:
