Ensure that "pg_restore -l" reports dependent TOC entries correctly.

Ensure that "pg_restore -l" reports dependent TOC entries correctly.

If -l was specified together with selective-restore options such as -n
or -N, dependent TOC entries such as comments would be omitted from
the listing, even when an actual restore would have selected them.
This happened because PrintTOCSummary neglected to update the te->reqs
marking of the entry they depended on.

Per report from Justin Pryzby.  This has been wrong since 0d4e6ed30
taught _tocEntryRequired to sometimes look at the "reqs" marking of
other TOC entries, so back-patch to all supported branches.
