openjade/sgml-common: Add sstate postrm commands

If you bump the PR of sgml-common and openjade-native but not sgml- common-native, you will see a failure as files were removed from the sysroot but still referenced by the sgml docbook catalog.

To properly handle this, the clean function needs to run at sstate removal time, the problem is that this sstate removal can happen when the metadata isn't present, so the correct removal commands are unknown.

To avoid this, we need to write the commands into a "postrm" script when we install the files, this can then be executed at sstate removal time.
