Fix failing viewport-collision render tests

[ChrisLoer]

The following tests pass locally for me but give different results on some of our CI environments:

debug/collision-lines-pitched
debug/collision-lines
text-pitch-alignment/viewport-overzoomed-single-glyph
text-pitch-alignment/viewport-text-depthtest

text-pitch-alignment/viewport-overzoomed-single-glyph and text-pitch-alignment/viewport-text-depthtest are fixed.

I switched debug/collision-pitched-wrapped over to this issue. It was previously ignored against issue #3841, but it looks like theres an actual difference in collision result now, not just a difference in how collision boxes are rendered.

Per @brunoabinader 's comment in mapbox/mapbox-gl-js#6250 (comment), I added ignores for real-world/{bangkok,chicago,sanfrancisco targeting this issue.
