spirv-reader: convert coordinate type when unsigned 

In SPIR-V, coordinates for ImageRead, ImageFetch, ImageWrite are
integral.  When they are unsigned, they must be converted to signed.

Fix tests for image sampling and dref sampling that used integer
coordinates. SPIR-V requires them to be floating point.
