[PATCH 2/9] msi: Add support for exporting the _SummaryInformation table.

From: "Erich E. Hoover" <erich.e.hoover at gmail.com>
The _SummaryInformation table stores a lot of important information
about an MSI database. This patch adds the ability to export that
table since, like _ForceCodepage, it is stored in a different format
than the other tables.
v2: Avoid lstrlenA calls.
