Restrict lo_import()/lo_export() via SQL permissions not hard-wired checks.

While it's generally unwise to give permissions on these functions to
anyone but a superuser, we've been moving away from hard-wired permission
checks inside functions in favor of using the SQL permission system to
control access. Bring lo_import() and lo_export() into compliance with
that approach.

In particular, this removes the manual configuration option
ALLOW_DANGEROUS_LO_FUNCTIONS. That dates back to 1999 (commit 4cd4a54c8);
it's unlikely anyone has used it in many years. Moreover, if you really
want such behavior, now you can get it with GRANT ... TO PUBLIC instead.
