Boo... Using -fbo with an ES1 test *should* work. If a context doesn't supports
fbos, the Piglit framework is supposed to gracefully to fallback to running the test
without an fbo. the eglTerminate in the fallback path causes a segfault in i965. That's
right: our driver dies horrifically if the user calls eglTerminate. Last time I checked,
the the problem was that the intel_context gets deleted *after* the intelScreen, despite
the context belongs to the screen.

I posted Piglit tests for this bug a long time ago, but they got ignored.
I'll repost them.

I see two ways to fix this: either fix eglTerminate, or rewrite how Piglit runs fbo tests.
