Shouldn't `jsonb_build_object` and `jsonb_build_array` be strict in this patch?
Otherwise one can get a segfault for these cases:

```
=# select jsonb_build_object(variadic NULL::text[]);
server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.

=# select jsonb_build_array(variadic NULL::text[]);
server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
```
