r300/compiler: do not set TEX_IGNORE_UNCOVERED on r500

The docs say it can be set for direct texture lookups, but even that
causes problems.

This fixes the wireframe bug:

NOTE: This is a candidate for the 7.9 and 7.10 branches.
(cherry picked from commit 6da4866ffdb19315bbb48f6778d1a5297b842a77)
