drm: reduce minimum build requirements

This patch adds the respective configure options to make it possible to disable
libdrm_intel, libdrm_radeon, libdrm_nouveau independently from each other.

NOTE:

The patch is based on work of Lucian Muresan <lucianm@users.sourceforge.net>
that fixes bug report:

  https://bugs.freedesktop.org/show_bug.cgi?id=29804

This one is adjusted to version 0.8.3 which doesn't support libkms yet.
