perf tests wp: Remove unused functions on s390

Fixing these build problems:

  tests/wp.c:24:12: error: 'wp_read' defined but not used [-Werror=unused-function]
   static int wp_read(int fd, long long *count, int size)
              ^
  tests/wp.c:35:13: error: 'get__perf_event_attr' defined but not used [-Werror=unused-function]
   static void get__perf_event_attr(struct perf_event_attr *attr, int wp_type,
               ^
    CC      /tmp/build/perf/util/print_binary.o
