s4-auth/unix_token: add new function auth_session_info_set_unix()

Used to fill the unix info in a struct auth_session_info similar to
auth_session_info_fill_unix().

The new auth_session_info_set_unix() receives the uid and gid for
the unix token as an parameter. It does not query the unix token from
winbind (via security_token_to_unix_token()).
This is useful to fill a user session info manually if winbind is not
available.
