Use libdrm to lookup pipe for tear-free sync of XV
Previously, the code was trying to examine a driver_private field,
but those fields are only set by the userland-modesetting code so
would fail in the case of KMS. This fixes bug #21076:
[945GME] [KMS] XV_SYNC_TO_VBLANK does not prevent tearing of xv video
