Update to upstream wolfssl 5.7.2

Moving from v5.6.6-stable we are picking up:
https://github.com/wolfSSL/wolfssl/releases/tag/v5.7.0-stable
https://github.com/wolfSSL/wolfssl/releases/tag/v5.7.2-stable
(there was no 5.7.1)

Our `disable-falcon-dilithium.patch` required an update, likely due to the
changes in wolfSSL/wolfssl#7622.
