Subject: [PATCH 82/83] files: add session recording flag

If session recording is configured for a group the NSS ans PAM
responder rely on a attribute in the cache set by the backend to
determine is session recording is configured for the user or not. This
flag is typically set during the initgroups request.

Since the files provider does not have a dedicated initgroups request
the attribute must be set otherwise. This patch sets is for all users
after the files are reloaded.
