package/wolfssl: security bump to version 4.5.0

wolfSSL version 4.5.0 contains 6 vulnerability fixes: 2 fixes for TLS 1.3,
2 side channel attack mitigations, 1 fix for a potential private key leak
in a specific use case, 1 fix for DTLS including those 3 CVEs:

- Fix CVE-2020-12457: An issue was discovered in wolfSSL before 4.5.0.
  It mishandles the change_cipher_spec (CCS) message processing logic
  for TLS 1.3. If an attacker sends ChangeCipherSpec messages in a
  crafted way involving more than one in a row, the server becomes stuck
  in the ProcessReply() loop, i.e., a denial of service.
- Fix CVE-2020-15309: An issue was discovered in wolfSSL before 4.5.0,
  when single precision is not employed. Local attackers can conduct a
  cache-timing attack against public key operations. These attackers may
  already have obtained sensitive information if the affected system has
  been used for private key operations (e.g., signing with a private
  key).
- Fix CVE-2020-24585: An issue was discovered in the DTLS handshake
  implementation in wolfSSL before 4.5.0. Clear DTLS application_data
  messages in epoch 0 do not produce an out-of-order error. Instead,
  these messages are returned to the application.

Also update hash of LICENSING as well as WOLF_LICENSE due to later
verbage update with
