generators: Add the default precision for floats in GLSL ES shaders
In GLSL ES fragment shaders there is no default precision for floats.
The generated shaders are using floats in the return type of a
function. These had undefined precision which should be invalid.
Mesa has started detecting this since 95927c414ff.
