stringutil: edit comment to reflect actual data type name
In development the data type used to hold an email/name pair
was called a "mailmaptup" since it was implemented as a
namedtuple. The implementation has since been changed to use
an @attr.s decorated class named mailmapping. This commit
changes a comment to reflect this change.
