[Piglit] [PATCH] Handle OpenGL ES-CM 1.x strings in piglit_get_gl_version

[Matt Turner]

Otherwise, piglit would fail to parse the version string and report a
failure if glGetString(GL_VERSION) were called in an ES 1.x context.

I'm not sure why we need this check at all and can't just eat characters
while(!isdigit(*c) && *c != NULL).

The piglit_is_gles() function immediately above won't handle GLESv1 either
but I'll leave that for later.
