Enable OpenSSL compiling in Linux

In order to compile APFS decryption code, the flag HAVE_LIBOPENSSL must be defined. However, even after running ./configure and the output shows the output bellow and the flag is not defined.

Building:
   openssl support:                       yes

   afflib support:                        yes
   libewf support:                        yes
   zlib support:                          yes

   libbfio support:                       yes
   libvhdi support:                       yes
   libvmdk support:                       yes
   libvslvm support:                      yes
Features:
   Java/JNI support:                      yes
   Multithreading:                        yes

After run autoheader command, the flag HAVE_LIBOPENSSL came back to tsk_config.h.in. So the APFS decryption code was compiled.

PS: Using Ubuntu 22.04.

Btw, Ubuntu 22.04 has OpenSSL 3.0. So in order to avoid deprecated errors in compilation, the configure must be run with:

./configure CXXFLAGS="-Wno-error=deprecated-declarations"

Thank you @aberenguel!

@arisjr I wonder if APFS encryption support works on your environment without this, does it?

The patch I made should add HAVE_LIBOPENSSL if it has the dev libs test passed. I made a pull on tsk also https://github.com/sleuthkit/sleuthkit/pull/2781/files that shows the change, but this PR was closed after because I needed to remove the sleuthkit fork from my account.

The patch was tested by the issue creator and others and worked at the time, but I didn't test on all environments.

The patch I made was to be used with openssl 1.1x, the lib version that was tested when APFS support was made by the author (that has not being changed since then). I must say that using openssl 3 is somehow not tested.

On the ipeddocker, even using Ubuntu 22.04 as a base system, we made a "hack" to use Ubuntu 20.04 openssl 1.1 dev libs for compiling with the APFS support.

I must allocate some time to look it closely anyway. I'll take a look at the end of the day.
