[PATCH libdrm v2] xf86drm: use the correct device minor names on OpenBSD

[Jonathan Gray <jsg@xxxxxxxxx>]

Add defines for the device minor names and make use of them
in drmGetMinorName() so the correct paths will be used on OpenBSD.

v2: don't add new defines to xf86drm.h to keep them out of the API
    as requested by Emil.
