Fix parallel-safety markings for contrib/dblink. 

As shown by buildfarm reports, dblink_build_sql_insert and
dblink_build_sql_update are *not* parallel safe, because they
may attempt to access temporary tables of the local session.

Although dblink_build_sql_delete doesn't actually touch the
contents of the referenced table, it seems consistent and prudent
to mark it PARALLEL RESTRICTED too.
