Bug#795977: dahdi-tools: please make the build reproducible

Source: dahdi-tools
Version: 1:2.10.2-2

Hi,

While working on the "reproducible builds" effort [1], we have noticed
that dahdi-tools could not be built reproducibly.

The attached patch sets the timezone to UTC before calling asciidoc to
avoid timezone differences in the generated docs. Once applied,
dahdi-tools can be built reproducibly in our current experimental framework.
