[debian-mysql] Bug#1010846: mariadb-common: Removes directory /etc/mysql/mariadb.conf.d during uninstall preventing mysql server from starting

[Nick DeYarman]

Package: mariadb-common
Version: 1:10.5.15-0+deb11u1
Severity: normal
X-Debbugs-Cc: 1nick1 at gmail.com

After installing mailutils which uses mariadb-common as a
dependency, I uninstalled mailutils and ran `apt autoremove`
which removed mariadb-common. mysql server then ran into a fatal
error as /etc/mysql/my.cnf contains the line "!includedir /etc/mysql/mariadb.conf.d/" in its default configuration.

Re-making the directory /etc/mysql/mariadb.conf.d solves the issue.
