glsl: Parse 0 as a preprocessor INTCONSTANT
This allows a more reasonable error message for '#version 0' of
0:1(10): error: GLSL 0.00 is not supported. Supported versions are: 1.10, 1.20, 1.30, 1.00 ES, 3.00 ES, 3.10 ES, and 3.20 ES
instead of
0:1(10): error: syntax error, unexpected $undefined, expecting INTCONSTANT
