Updates the install dependencies for Debian 9 'stretch'

This updates the dependencies for an installtion on Debian 9 'stretch'. The package libmysqlclient-dev is no longer available on Debian 9, therefore we need to install the (meta) package default-libmysqlclient-dev, which points to libmariadbclient-dev-compat and is compatibl to libmysqlclient-dev.
