[Libva] [PATCH] dummy_drv_video: add back VA_DRIVER_INIT_FUNC definition for __vaDriverInit_*()

[Vincent Bernat]

Since commit ca1798e77b6fa99dbb010f202a057f75415afd52, dummy driver
was defining VA_DRIVER_INIT_FUNC symbol instead of __vaDriverInit_0_33
and therefore cannot be used for testing anymore. We restore the
definition of this symbol in configure.ac.
