Fix message reduction error

The unified logging system (aka OSLog) expects a OSLogMessage and does
not allow just passing in a string variable. Instead the variable has to
be interpolated into a string literal, which sets the default privacy
setting to 'private' and hence reducts the whole message.
This commit sets the privacy setting to 'public'.
