Build mysql-connector-python from source (#50)

mysql-connector-python fixed builds from source as of 9.3.0 (https://bugs.mysql.com/bug.php?id=113396)

mysql-connector-python 9.3.0+ does not support Python 3.8

Since no binary packages are available for s390x, building from source will be needed to build a s390x charm
