[ima-evm-utils][PATCH v2 1/4] Call OPENSSL_Cleanup before main exit to avoid crashes when engine was used

[Stefan Berger <stefanb@xxxxxxxxxxxxxxxxxx>]

From: Stefan Berger <stefanb@xxxxxxxxxxxxx>

When OPENSSL_Cleanup is called via destructor after main() was left then
evmctl crashes on Ubuntu 24.04 (Noble). This can be avoided by calling
OpenSSL_Cleanup explicitly before leaving main().
