pgbouncer init script does not create /var/run/postgresql directory

The pgbouncer init script uses a PIDFILE in /var/run/postgresql, but that
directory is not created by the init script, so after a reboot, pgbouncer will
not start.

It probably should do something like the postgresql init script does:

    if [ -d /var/run/postgresql ]; then
        chmod 2775 /var/run/postgresql
    else
        install -d -m 2775 -o postgres -g postgres /var/run/postgresql
    fi
