Fix parsing error with SPIR-V negating a uint.

Our SPIR-V code generator did not implement support for negating a uint.
However, this is something that GLSL allows (as does the rest of SkSL).
I checked glslang and it uses OpSNegate here. The SPIR-V docs indicate
that OpSNegate allows any type of integer, and the validator lets it
pass, so we now use OpSNegate here as well.
