package/redis: bump to 5.0.6

The release notes at
https://raw.githubusercontent.com/antirez/redis/5.0/00-RELEASENOTES
say:

==
Upgrade urgency CRITICAL: Only in case of exposed instances to untrusted users.

This Redis release, 5.0.6, is a bugfix and enhancement release. The most
important bugfix is a corruption related to the HyperLogLog. A malformed
HyperLogLog string could cause an invalid access to the memory. At a first
glance the vulnerability appears to be not exploitable but just a DoS. The
way to trigger the issue is complex, we'll not provide any information about
how to do that for the users safety.
