Tony Nguyen ef57371a92 Do not enable stack tracer for ZFS performance test
Linux ZFS test suite runs with /proc/sys/kernel/stack_tracer_enabled=1,
via zfs.sh script, which has negative performance impact, up to 40%.

Since large stack is a rare issue now, preferred behavior would be:
- making stack tracer an opt-in feature for zfs.sh
- zfs-test.sh enables stack tracer only when requested
