Bug#1077479: debcraft: please make the build reproducible

Source: debcraft

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
debcraft could not be built reproducibly.

This is because it embeds the current value of DEB_BUILD_OPTIONS in
its manpage, which, of course, can vary between builds:

 -be honored (currently DEB_BUILD_OPTIONS='buildinfo=+all reproducible=+all parallel=42 ').
 +be honored (currently DEB_BUILD_OPTIONS='buildinfo=+all reproducible=+all parallel=20 ').

A patch is attached that strips this from the statically-generated
Makefile. The dynamic variable still can be seen when invoking
"debcraft --help".
