Update afl to 1.95b:

--------------
Version 1.95b:
--------------

  - Fixed a harmless bug when handling -B. Spotted by Jacek Wielemborek.

  - Made the exit message a bit more accurate when AFL_EXIT_WHEN_DONE is set.

  - Added some error-checking for old-style forkserver syntax. Suggested by
    Ben Nagy.

  - Switched from exit() to _exit() in injected code to avoid snafus with
    destructors in C++ code. Spotted by sunblate.

  - Made a change to avoid spuriously setting __AFL_SHM_ID when
    AFL_DUMB_FORKSRV is set in conjunction with -n. Spotted by Jakub Wilk.
