Running glmark2 on imx6 with kernel 4.11.4 and Mesa 17.1.2 leads to
a segmentation fault.
Apply Lucas Stach's patch to fix the problem while upstream glmark2
doesn't get fixed.

+Subject: [PATCH] NativeStateDRM: use fixed event context version
+
+Using the latest version is not a good idea, as the context content may
+change between versions.
+
+Fixes a segfault with new kernel and libdrm.
