drm_hwcomposer: Use correct DRM event context version

Explicitly declare which DRM event context version we want to use,
rather than just the latest one libdrm supports. New versions may change
semantics, or extend the structure, in ways we're unaware of.

Stick with version 2, which is the version that introduced
page_flip_handler.
