LU-10447 tests: remove use of SETSTRIPE from sanity

LU-10447 tests: remove use of SETSTRIPE from sanity

The recently landed test_136() was using $SETSTRIPE instead of
$LFS setstripe, but that was removed from test-framework.sh in a
later patch (written earlier and didn't take it into account).
This test doesn't fail during normal testing because it is skipped
due to SLOW testing.  Change it to use $LFS setstripe instead.

Fixes: cc1092291932 ("LU-13069 obdclass: don't skip records for wrapped catalog")
Fixes: be3b7e772d3a ("LU-10447 tests: deprecate use of $SETSTRIPE/$GETSTRIPE")
Test-Parameters: trivial testlist=sanity env=ONLY=136,ONLY_REPEAT=10
