[MISC] 8.4 - Fix rock building

[sinclert-canonical]

This PR fixed rock building of the charmed MySQL 8.4 rock, in order to unlock further development.

Seems like something changed, either in the rockcraft or in the core24 snaps since the last time we built the rock, so that now package collisions in the first defined part crash the build process. I did a full audit of what is needed and by who, running the following commands:

# Within my local shell
sudo rockcraft pack
sudo rockcraft.skopeo --insecure-policy copy oci-archive:charmed-mysql_8.4.8_amd64.rock docker-daemon:sinclert/charmed-mysql:8.4-test
sudo docker run --rm -it sinclert/charmed-mysql:8.4-test &
sudo docker exec -it <container ID> bash

# Within the container shell
$ which logrotate
> ...
$ ldd /usr/bin/mysql
> ...
$ ldd /usr/bin/mysqlsh
> ...
$ ldd /usr/bin/mysqlrouter
> ...
$ ldd /usr/sbin/mysqld
> ...
