wolfssl: bump to 5.2.0

Fixes two high-severity vulnerabilities:

- CVE-2022-25640: A TLS v1.3 server who requires mutual authentication
  can be bypassed.  If a malicious client does not send the
  certificate_verify message a client can connect without presenting a
  certificate even if the server requires one.

- CVE-2022-25638: A TLS v1.3 client attempting to authenticate a TLS
  v1.3 server can have its certificate heck bypassed. If the sig_algo in
  the certificate_verify message is different than the certificate
  message checking may be bypassed.
