Bug#993540: libglvnd FTBFS with the nocheck build profile

[Helmut Grohne <helmut@subdivi.de>]

Source: libglvnd
Version: 1.3.4-1
Tags: ftbfs patch
User: debian-cross@lists.debian.org
Usertags: ftcbfs

libglvnd fails to build from source when enabling the nocheck build
profile and option. Its override_dh_auto_test is unconditionally run
(since the compatibility level is too low for debhelper to automatically
skip it) and runs xvfb-run, while xvfb is annotated <!nocheck>. Please
consider applying the attached patch to make it perform nocheck builds
(and cross builds) successfully.
