perf test: Fix vmlinux failure on s390x part 2

On s390x perf test 1 failed. It turned out that commit cf6383f73cf2 ("perf report: Fix kernel symbol adjustment for s390x") was incorrect.

The previous implementation in dso__load_sym() is also suitable for s390x.

Therefore this patch undoes commit cf6383f73cf2
