build: fix ngtcp2 crypto library detection

- Change library link check for ngtcp2_crypto_{gnutls,openssl} to
  to use function ngtcp2_crypto_recv_client_initial_cb instead of
  ngtcp2_crypto_ctx_initial.

The latter function is no longer external since two days ago in
ngtcp2/ngtcp2@533451f. curl HTTP/3 CI builds have been failing since
then because they would not link to the ngtcp2 crypto library.

Ref: https://github.com/ngtcp2/ngtcp2/pull/356

Closes https://github.com/curl/curl/pull/8372
