wolfssl: build with WOLFSSL_ALT_CERT_CHAINS

"Alternate certification chains, as oppossed to requiring full chain
validataion. Certificate validation behavior is relaxed, similar to
openssl and browsers. Only the peer certificate must validate to a trusted
certificate. Without this, all certificates sent by a peer must be
used in the trust chain or the connection will be rejected."

This fixes e.g. uclient-fetch and curl connecting to servers using a Let's
Encrypt certificate which are cross-signed by the now expired
DST Root CA X3, see [0].

This is the recommended solution from upstream [1].
