Update various places in Settings to use "admin" ueser flag instead of checking user id "0". This should be no-op in single user mode since the only admin user would be user 0. In split system user mode, this will correctly ACL admin user instead of non-interactive system user. Bug: 19913735 Change-Id: Ida4d59c5f689ea0dc34b3b3ff0822b087fa0afd6
