tools/xep227toprosody: Remove obsolete tool in favor of storage driver
This tool hasn't been updated for recent XEP-0227 changes, hasn't seen
many changes at all since its introduction and I don't remember anyone
mentioning ever using it.
Using mod_storage_xmlarchive and the migrator or the 3rd party
mod_migrate tool should work better these days and should be the way
forward.
