[PATCH] openssl: bump to 1.1.1k

[Eneas U de Queiroz]

This version fixes 2 security vulnerabilities, among other changes:

 - CVE-2021-3450: problem with verifying a certificate chain when using
   the X509_V_FLAG_X509_STRICT flag.

 - CVE-2021-3449: OpenSSL TLS server may crash if sent a maliciously
   crafted renegotiation ClientHello message from a client.

This was run-tested on WRT3200ACM (mvebu, armv7), using nginx, and
openssl util to encrypt & decrypt some files using software and the
devcrypto engine, since there have been some changes in the engine,
related to BSD compatibility, when opening the /dev/crypto device.
