circleci: Fix redis on Bionic. 

Fixes #11079.
Because of "service redis-server start" not working properly, in "do
Bionic hack" another instance of the server was being started. However,
once in a while this would fail for unknown reasons causing flakes in
tests involving redis. The cause of the service not starting was the
error:
::1:6379: bind: Cannot assign requested address
(see https://github.com/antirez/redis/issues/3241)
This is fixed by editing /etc/redis/redis.conf to not attempt binding
on IPv6. We change "do Bionic hack" to a simple sed command,
changing the appropriate line in the file.
By default, the line is "bind 127.0.0.1 ::1".
We change it to "bind 0.0.0.0".
