glsl: improve the accuracy of the radians() builtin function
The constant used in the radians() function didn't have enough
precision, causing a relative error of 1.676e-5, which is far worse
than the precision of 32-bit floats. This patch reduces the relative
error to 1.14e-9, which is the best we can do in 32 bits.
Fixes piglit tests {fs,vs}-radians-{float,vec2,vec3,vec4}.
