This is similar to commit 7420c9dab4aaf87e6b840410226c296c4668a48f
but for the i915 driver, as neeeded in android-x86.

In version v2, as per i965 implementation,
the extension GL_OES_EGL_image_external is not enabled by default.

The by-the-book way to enable the extension is mesa environment variable
MESA_EXTENSION_OVERRIDE="+GL_OES_EGL_image_external" to be set in init.rc
