Note: by default MDBF packages use a different path than official
distro's packages. IMO the behavior of distro is cleaner, so, make sure
that the directory exist in case we deploy MDBF packages.
Note2: the pid file option does not seem to be mandatory for systemd and
docker, so we might also decide to remove this option by default. But
for the moment it's probably cleaner/simpler to keep default options
deployed with packages.
Installing mariadb-backup with MariaDB-server is not working on Fedora
41 (it will install OS version). So, adapt the role so that we can use
case sensitive packages name. Also 10.11 was not provided for Fedora 41.
