Bug#981656: libxcb: reduce Build-Depends

[Helmut Grohne <helmut@subdivi.de>]

Source: libxcb
Version: 1.14-3
Tags: patch
User: helmutg@debian.org
Usertags: rebootstrap

libxcb participates in dependency loops relevant to architecture
bootstrap. Instead of looking into such a difficult problem, I looked
into easily droppable dependencies and found thre.

 * pthread-stubs are only required on non-linux architectures. I propose
   annotating it [!linux-any].
 * xsltproc is only used for rendering test results. I propose
   annotating it <!nocheck>.
 * dctrl-tools is entirely unused. I propose dropping it.

Please consider applying the attached patch.

Helmut
