mesa: Fix setup of ctx->Point.PointSprite for GLES2.

The recent change for GL core broke the older setup, which broke
gl_PointCoord on pre-gen6 (where gl_PointCoord is undefined if point
sprites are disabled).  Fixes the new piglit GLES-2.0/glsl-fs-pointcoord
test.

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=32429
Note: This is a candidate for the stable branches.
