Subject: [PATCH libdrm 2/7] CHROMIUM: vgem: add DRM_IOCTL_VGEM_MODE_MAP_DUMB
 support

This is the libdrm counterpart of the kernel patch in CL:263991:
DRM_IOCTL_MODE_MAP_DUMB is not allowable for use by render nodes, so we
add DRM_IOCTL_VGEM_MODE_MAP_DUMB, which behaves exactly the same as
DRM_IOCTL_MODE_MAP_DUMB, and is allowed on render nodes.

Old-TEST=the file /usr/include/libdrm/vgem_drm.h under the board's build
