Fix return value of shading language for GLES2.glsles

Throughout the mesa project we've been using 100 for GLES2's shading
language.  It was pretty clearly the intent here, but the clever
inline detection of "am I parsing a GLSL version or a GL version
string" forgot about GLSL 1.0.x, and thus returned 10.
