namespaces.7: Fix confusion caused by text reorganization
Since commit
ee81d7e41852, the flags list has been (only) above, not
below, these references.
(The flags table was added even before that, in commit
0b497138b908
("namespaces.7: Add table of namespaces to top of page"))
Fixes:
ee81d7e41852 ("namespaces.7: Include manual page references in the summary table of namespace types")
