mesa: return initial value for PROGRAM_SEPARABLE when not linked
From OpenGL ES 3.1 spec (7.12): "Most properties set within program objects are specified not to take effect until the next call to LinkProgram or ProgramBinary. Some properties further require a successful call to either of these commands before taking effect. GetProgramiv returns the properties currently in effect for program, which may differ from the properties set within program since the most recent call to LinkProgram or ProgramBinary, which have not yet taken effect. If there has been no such call putting changes to pname into effect, initial values are returned."
