[Reproducible-builds] Bug#795984: postgresql-plproxy: please make the build reproducible

Hi,

While working on the "reproducible builds" effort [1], we have noticed
that postgresql-plproxy 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,
postgresql-plproxy can be built reproducibly in our current experimental
framework.
