Subject: [PATCH 2/3] perf tests: Remove bash construct from record+zstd_comp_decomp.sh

Commit 463538a383a2 ("perf tests: Fix test 68 zstd compression for
s390") inadvertently removed the -g flag from all platforms rather than
just s390, because the [[ ]] construct fails in sh. Changing to single
brackets restores testing of call graphs and removes the following error
from the output:

  $ ./perf test -v 85
  85: Zstd perf.data compression/decompression                        :
  --- start ---
  test child forked, pid 50643
  Collecting compressed record file:
  ./tests/shell/record+zstd_comp_decomp.sh: 15: [[: not found

Fixes: 463538a383a2 ("perf tests: Fix test 68 zstd compression for s390")
