Alberto Bertogli a1b6821ce1 dkim: Make timestamp parsing more robust against overflow ...

The timestamp string in the t= and x= headers is an "unsigned decimal
integer", but time.Unix takes an int64. Today we parse it as uint64 and
then cast it, but this can cause issues with overflow and type
conversion.

This patch fixes that by parsing the timestamps as signed integers, and
then checking they're positive.
