Recurse to sequences on ownership change for all relkinds

When a table ownership is changed, we must apply that also to any owned
sequences.  (Otherwise, it would result in a situation that cannot be
restored, because linked sequences must have the same owner as the
table.)  But this was previously only applied to regular tables and
materialized views.  But it should also apply to at least foreign
tables.  This patch removes the relkind check altogether, because it
doesn't save very much and just introduces the possibility of similar
omissions.
