Move web-build into Debian build rules

This removes the convoluted steps in docker-build.sh in favour of
integrating the web-build sequence into the Debian rules file
explicitly. This will allow the web-build to work properly outside of
the boutique Docker container we build, thus allowing it to be build
properly directly on a target system with dpkg-buildpackage.
