ldns: specify OpenSSL 1.1 APIs

OPENSSL_API_COMPAT can be used to specify the OpenSSL API version in
use for the purpose of hiding deprecated interfaces and enabling
the appropriate deprecation notices.

This change is a NFC while we're still using OpenSSL 1.1.1 but will
avoid deprecation warnings upon the switch to OpenSSL 3.0.

A future ldns update should migrate to use the OpenSSL 3.0 APIs.

This is a recommit of c6750ddec917 after the ldns update in
5afab0e5e56f.

Revert "Require the OpenSSL 1.1 APIs when compiling ldns"

This particular change appears to have broken the build; the change
needs some massaging to work with OpenSSL 1.1.

This reverts commit c6750ddec9177b67bb4883717933e87ac24a3a44.

Require the OpenSSL 1.1 APIs when compiling ldns

Moving the APIs from OpenSSL 1.1 supporting APIs to 3.x supporting APIs
is a non-trivial effort. Require 1.1 API compatibility to unblock
updating OpenSSL in base to 3.x.

This mirrors what upstream has done in their configure.ac file.

LDNS needs OpenSSL. This wasn't a problem as long as it was only build
statically, since any program using it would have to link with it anyway.
