Subject: [PATCH] Allow accessing raw created/modified FILETIME

This is necessary to correctly compute the authenticode hash of an MSI
file[0]. While it's technically possible to get the FILETIME back from
the SystemTime, it's a lossy operation (a FILETIME that doesn't fit in
a SystemTime returns UNIX_TIME). It'd be nicer to just have access to
the raw value so we can guarantee we're hashing the correct value.
