Update tsk/tsk_config.h.in

[aberenguel]

I've seen the file tsk/tsk_config.h.in has not the flag HAVE_LIBOPENSSL set.

So, just running ./boostrap and ./configure is not enough to enable SSL.

As the file tsk/tsk_config.h.in is versioned, it would be better to add the updated version after run autoheader.
