[oe] [PATCH][meta-qt5 3/7] qtwebengine: add dependency on libxscrnsaver with x11 in DISTRO_FEATURES

[Martin Jansa]

* when qtbase is built with x11 support, xcb is enabled in QT_CONFIG
  and qtwebengine checks for libxscrnsaver.
  Unfortunately such check isn't fatal for do_configure task, it will
  only show something like this:
  libxscrnsaver wasn't found, qtwebengine won't be built
  in log.do_configure and continue to do_compile and do_install (which
  will also finish successfully, saying "Nothing to do").
