Fix deb package recommended dependencies (#4176)

When a package upgrade needs installing other dependency packages, `apt
upgrade` do not update the package to avoid adding other packages. You
have to use `apt dist-upgrade` or `apt install`.

By default, apt installs recommended dependencies. so having couchdb as
a recommended dependency blocks simple package upgrade from our legacy
package on debian buster.

This PR removes couchdb recommended dependency to ease debian buster
migration
