x-terminal-emulator is a virtual package, which doesn't get reported by package, so I decided to go with 'executable' resource instead.

This, OTOH, requires unreleased version of plainbox-provider-resource, as x-terminal-emulator is a symlink. More info: https://bugs.launchpad.net/plainbox-provider-resource/+bug/1710172

Everything works nicely provided with ppr supplied from master.
