i965: Don't create a swrast context on ES2+.

We already skip this for API_OPENGL_CORE; ES2+ is very similar.
The primary user of the swrast context is GL_SELECT and GL_FEEDBACK,
which have never existed in ES.

This saves approximately 18MB of memory in GLBenchmark 2.7 Egypt (ES2).
No regressions in es3conform on Ivybridge.
