Replace two identical debian/control files with a single one

The only difference between the files was the Debian standards
line by one micro version. There was no logical motivation why
there was separate control file for Debian and Ubuntu.

The new debian/control file lives directly at the correct location
and has the correct contents.

Modify autobake.sh to take into account new control file location.

debian/autobake-deb.sh
