ssl: Include limits.h to get INT_MAX when using LibreSSL

When compiling against OpenSSL, the <limits.h> header is indirectly
included via openssl/ossl_typ.h from openssl/conf.h, but the LibreSSL
version of ossl_typ.h does not include <limits.h> which cause compiler
failure due to missing symbol (since ffd080d94fe). Fix by explicitly
including <limits.h>.
