Jack Mordaunt 24b0c2a4a1 internal/gl: [Windows] allow GetProgramInfoLog to return nothing

If GetProgrami returns 0 we will panic because a zero-sized buffer indexed
at zero will OOB panic: "runtime error: index out of range [0] with length 0".

This was observed and is not theoretical.

Windows 8 9200
