[PATCH v5 3/3] box: get rid of atexit() for calling cleanup routines

[Serge Petrenko <sergepetrenko@tarantool.org>]

Move a call to tarantool_free() to the end of main().
We needn't call atexit() at all anymore, since we've implemented
on_shutdown triggers and patched os.exit() so that when exiting not
due to a fatal signal (when no cleanup routines are called anyway)
control always reaches a call to tarantool_free().
