[Buildroot] [PATCH 1/1] package/redis: security bump to v6.2.0

[Titouan Christophe]

This version also needs a patch from upstream to compile on musl systems.

>From the release notes:
================================================================================
Redis 6.2.0 GA  Released Tue Feb 22 14:00:00 IST 2021
================================================================================

Upgrade urgency: SECURITY if you use 32bit build of redis (see bellow), MODERATE
if you used earlier versions of Redis 6.2, LOW otherwise.

Integer overflow on 32-bit systems (CVE-2021-21309):
Redis 4.0 or newer uses a configurable limit for the maximum supported bulk
input size. By default, it is 512MB which is a safe value for all platforms.
If the limit is significantly increased, receiving a large request from a client
may trigger several integer overflow scenarios, which would result with buffer
overflow and heap corruption.
