package/odb: add dependency on host-libodb

host-odb installs the ODB compiler, which when executed at runtime,
needs access to the libodb headers. This is a runtime dependency,
normally added in Config.in, but for host packages there is no way to
express a runtime dependency. In order to have them installed, add a
dependency on host-libodb.
