xfree86: Xorg.wrap: Do not require root rights for cards with 0 outputs

Prior to this commit the Xorg.wrap code to detect if root rights are
necessary checked for DRM_IOCTL_MODE_GETRESOURCES succeeding *and*
reporting more then 0 output connectors.

DRM_IOCTL_MODE_GETRESOURCES succeeding alone is enough to differentiate
between old drm only cards (which need ums and thus root) and kms capable
cards.

Some hybrid gfx laptops have 0 output connectors on one of their 2 GPUs,
resulting in Xorg needlessly running as root. This commits removes the
res.count_connectors > 0 check, fixing this.
