[PATCH 2/2] mesa-dri: move extra DRIMODULES to EXTRA_DRIMODULES

[Martin Jansa <martin.jansa@gmail.com>]

* this way we can use
  EXTRA_DRIMODULES_armv4t += ",glamo" in meta-openmoko layer and
  EXTRA_DRIMODULES_armv4t += ",foo" in meta-bar layer without knowledge
  of other modules in other layers in stack
