A "@type copy" statement is already present at the beginning of each
match element, so extra "type copy" are not needed. They are causing the
following warnings in fluentd logs:

[warn]: parameter 'type' in <match syslog.local0.**>
[warn]: parameter 'type' in <match syslog.local1.**>

This commit also harmonizes indentation of the Monasca config block.
