couchdb-bin.postinst creates "couchdb" user, but couchdb-bin.postrm doesn't remove it

[Jason Gerard DeRose]

Even after this, the "couchdb" user and group will still remain:

sudo apt-get purge couchdb couchdb-bin

The `couchdb-bin.postinst` script creates the "couchdb" user and group, and the `couchdb-bin.postrm` script should really remove it.

This would be a nice thing to SRU so that it's possible to have a prim-and-proper upgrade to a newer CouchDB package:

This is by design. System users should not be removed on package removal.
