OpenSSL 4.0 constified X509_get_subject_name(), so assigning its result to an X509_NAME * no longer compiles. The name is only read here, and X509_set_issuer_name() already accepts a const name, so a const local builds against both 3.x and 4.x.

OpenSSL 4.0 returns a const X509_NAME pointer from X509_get_subject_name() and removed the ENGINE API from libcrypto, so libaktualizr fails to compile and then to link: crypto.cc:625:45: error: invalid conversion from 'const X509_NAME*' to 'X509_NAME*' [-fpermissive] crypto.cc:149: undefined reference to 'ENGINE_load_private_key' Add the const fix submitted as uptane/aktualizr#138 and the patch submitted as uptane/aktualizr#139 that only compiles the engine-backed key loading with BUILD_P11. Builds without the hsm feature now link against OpenSSL 4.0; builds with it fail early at compile time until the PKCS#11 support is ported to OpenSSL providers.
