[remove] Please remove old stale binary postgresql-11-rdkit from focal

[Christian Ehrhardt ]

As part of getting rid of the remaining postgresql-11 dependencies please remove postgresql-11-rdkit from focal.

This was built by an older version of the package:
root@f:~# apt-cache show postgresql-11-rdkit
Package: postgresql-11-rdkit
Architecture: amd64
Version: 201903.1-2ubuntu1
...

It has no dependencies left:
$ reverse-depends -r focal postgresql-11-rdkit
No reverse dependencies found

And was superseded by a -12 version
root@f:~# apt-cache show postgresql-12-rdkit
Package: postgresql-12-rdkit
Architecture: amd64
Version: 201909.1-2ubuntu1
...
