Jonas Ådahl e6421dc5da kms: Have the device impl open device files themself
This changes the way the KMS backends load; if we're headless, we always
use the dummy one and fail otherwise; in other cases, we first try the
atomic backend, and if that fails, fall back on the simple one.

The aim for this is to have the impl device open and close the device
when needed, using the device pool directly.
