UPDATE security/polarssl-2.16.12

This release of Mbed TLS provides bug fixes and minor enhancements, and
includes a fix for CVE-2021-44732 (double free in
mbedtls_ssl_set_session() in an error case). More info can be found at
https://tls.mbed.org/tech-updates/security-advisories/mbedtls-security-advisory-2021-12.

Overview on changes can be found at
https://github.com/ARMmbed/mbedtls/releases/tag/v2.16.12.

Note that this is the last release of the 2.16 long-time support branch.
Guess we should soon update this port to the 2.28 branch, which is the
new LTS branch and will be supported for at least 3 years.

Passes all tests.
