xserver-xorg: restore packaging for the DRI/DRI2/DBE extensions
Even though the current xserver in oe-core (1.13) doesn't ship these as
standalone extensions, older X servers required by binary drives
(e.g. meta-intel's 1.9) still install them separately. As the packages didn't
exist in xserver-xorg.inc the extensions were not packaged, and X didn't work.
Revolve this by restoring the package definitions, and moving the upgrade path
dependencies to xserver-xorg_1.13.bb.
