description:
add new INTEL_DRIVER_DATE variable that defaults to 2019, but can
be set to 2014 and the older KMS based driver will be used (which
is the last actual release.)

this fixes some display issues on older systems.  for me, sandy
bridge has minor issues with the new drivrer, but kaby lake really
likes to have the newer driver.

perhaps change default later, but this enables simple testing.
