dpkg-deb --build reads a binary control file and rejects the two-stanza
source+binary format. Rewrote control.j2 as a single binary-only stanza.
Removed the source stanza (Source, Standards-Version, Build-Depends fields)
which are only meaningful in source packages built with dpkg-buildpackage.

REST_CLIENT_PATH was defined but never referenced. REST/Client.pm is owned
by librest-client-perl and is intentionally not removed by our postrm
(documented in the comment above remove_plugin_files). Remove the dead variable.
