build: explicitly disable libsecp256k1 openssl based tests

These tests are failing when run against OpenSSL 3, and have been
removed upstream, https://github.com/bitcoin-core/secp256k1/pull/983, so
disabled them for now to avoid `make check` failures.

Note that this will also remove warning output from our build, due to
the use of deprecated OpenSSL API functions. See #23048.
