When 'stage' is used with <traverse-dependencies>on, do not follow the <use>

property, since it's typically used when only headers are used.

* build/virtual-target.jam (subvariant.all-referenced-targets): Return
  the names of properties.
* tools/stage.jam (stage-target-class.collect-targets): Filter out <use>

Thanks to Jurgen Hunold for the bug report.
