Subject: [PATCH 3/3] Remove engine related parts for OpenSSL 3.0
OpenSSL just cannot work with mixing ENGINE_* api mixed with OSSL_PARAM
builders. But it can be built in legacy mode, where deprecated but still
working API would be used.
It can work under OpenSSL 3.0, but only if using legacy code paths
matching OpenSSL 1.1 calls and functions.
Remove fromlabel processing by OpenSSL 3.0 only functions. They can
return later with a proper provider support for pkcs11.
