Remove extra space from my.cnf to fix idempotency

The upstream galera module creates the .my.cnf to use when setting up
galera but it checks for the password existing in the file without a
space between password and the value. This change removes the extra
spaces between the values to satisfy the check condition and prevent the
.my.cnf from being overwritten each time the database task is run.
