QSql/MariaDB/MySQL: use utf-8 as encoding for username and password

The mariadb driver sets the encoding for the connection to utf-8 but
only after the username and password was already set. Therefore
non-ascii characters were not correctly encoded when the local character
set was not the default one from the database.
Move mysql_set_character_set() above the username/password setting and
encode all as utf-8 instead local8Bit.
