OpenSSL_add_all_algorithms() is deprecated since OpenSSL 1.1.0, use it accordingly

OPENSSL_API_COMPAT is to be set by the module
including OpenSSL header to request a certain
API level compatibility, and starting with
OpenSSL 3, it's no more defined by OpenSSL
header to the default API level.

OPENSSL_VERSION_NUMBER must be used instead.

Fixes the-tcpdump-group#977
