Avoid locale-dependent output in select_views regression test.

Use 'COLLATE "C"' to force locale-independent sorting of the iexit
view results in select_views.sql.  We aren't particularly interested
in the exact sorting behavior here, and this doesn't change the shape
of the generated plan, so it seems like a wash as far as the goals
of this test go.

This is in response to bug #14637 from Tomasz Kontusz.  It doesn't
fully resolve his problem, because he also saw some diffs in the
create_index test.  But other people have had issues with select_views
too, and this fix lets us drop the select_views_1.out variant expected
file altogether, which is a nice win from a maintenance standpoint.
