Use per user info for seinfo

The full seinfo context contains a piece that's per application
[eg. target sandbox] and a piece that's per user [eg. if the
application is 'instant' or 'full]. When we reconciled the data
directory for the application, we were only using the static
parts. We now add the user specific parts.
