targets/dri-swrast: convert to gallium megadrivers :)

Export the approapriate new symbol, and keep backwards compat
via the megadriver_stub helper library.

Our next step would be to unify dri/drm and dri/sw, leading to
a complete megadrivers solution, and having a single library
that provides dri across all targets.
