Merge pull request #6 from fi01/test

Update addresses for ISW13F, IS17SH, Sony Tablet S/P, SH-04E.
Use diag_run_exploit
Try get_creds_functions_addresses before find_creds_functions_in_memory(), now it works on SH-04E.
  BUG: perf_swevent_run_exploit() works correctly only once. After it calls find_creds_functions_in_memory(), kernel will crash in run_obtain_root_privilege.
Support SOL21
