Bug#981133: libxkbcommon: reduce Build-Depends

[Helmut Grohne <helmut@subdivi.de>]

Source: libxkbcommon
Version: 1.0.3-2
Tags: patch
User: helmutg@debian.org
Usertags: rebootstrap

libxkbcommon participates in dependency loops relevant to architecture
bootstrap. Instead of looking into such a difficult problem, I looked
for easily droppable dependencies.

An obvious one is cmake as libxkbcommon now uses meson.

libx11-dev is less obvious. libxkbcommon now uses libxcb a lot and does
not use any libx11-dev header.

I'm not sure what xutils-dev was ever used for. I couldn't locate any
use of it anywhere in libxkbcommon or an explanation in a changelog.
Maybe it was build with xmkmf at an earlier time? I suggest dropping it
as well.

x11-xkb-utils and xkb-data are less obvious. I'm not sure whether
they're completely unused or whether they're used in tests. The safe bet
is annotating them <!nocheck>, but maybe removing them is better.

Since libxkbcommon is normally reproducible, one can verify the
correctness of this change. A regular build produces the very same
binary artifacts as a nocheck build with all of the mentioned
dependencies turned into Build-Conflicts. Please consider applying the
attached patch.

Helmut
