Support more distributions in the AppArmor profiles

Summary:
This fixes Akonadi on Arch Linux (and possibly others).

Changes to the AppArmor profiles:

- Allow writing and locking `/run/user/${uid}/akonadi`, the database engine socket is stored there.
- Add `abstractions/consoles`, needed for console output.

PostgreSql specific:
- Add bash (it is a common default shell).
- Support `/usr/bin/*` paths for PostgreSQL binaries.
- Support `pg_upgrade`.

MySQL specific:
- Add bash (it is a common default shell).
- Add `/usr/bin/mysqld` as a path for the MySQL daemon binary.
- Add `abstractions/openssl`. When using MySQL, both `akonadiserver` and `mysqld` will try to read `/etc/ssl/openssl.cnf`.
- Add `/etc/my.cnf` and `/etc/my.cnf.d/`, on Arch Linux the `my.cnf` configuration is stored there.

Test Plan: `akonadictl start` on a system with active AppArmor and loaded profiles.
