Fix failing TextureViewTest

A tiny scaleX/scaleY is sneaking into the matrix,
throwing off the nearest/bilerp calculation.

This tiny scaleX/scaleY appears to be coming from
the inverse texture matrix necessary to workaround
skia issue https://bugs.chromium.org/p/skia/issues/detail?id=7075

So add another workaround for SkMatrix::getType()
reporting this as having a scale, even though there really
isn't one.
