remove debian packaging products (log, substvars) from version control
remove include directory from hubo-ach package

This was causing a collision between hubo-ach and hubo-ach-dev that
makes the debs unusable. It was also somewhat against standard
packaging conventions.
remove leading / from lines in hubo-ach-dev.install

Two reasons:
* To maintain style through the file
* I suspect that the leading / will break things if someone tries to
  make a deb with the install prefix changed
