sign-file,extract-cert: use pkcs11 provider for OPENSSL MAJOR >= 3

commit 558bdc45dfb2669e1741384a0c80be9c82fa052c upstream.

ENGINE API has been deprecated since OpenSSL version 3.0 [1].
Distros have started dropping support from headers and in future
it will likely disappear also from library.

It has been superseded by the PROVIDER API, so use it instead
for OPENSSL MAJOR >= 3.
