[Piglit] [PATCH 2/4] arb_texture_view: Constrain accessible mip levels correctly

[Chris Forbes]

The test expects us to be sampling from the smallest miplevel accessible
in the view, but the TEXTURE_MAX_LEVEL constraint was out of range,
and TEXTURE_BASE_LEVEL wasn't set at all.

This would have been masked previously because the test fell over due to
use of legacy features in the core profile.
