qttools-native: Add module

* QtTools provide optional tools like "lupdate, lrelease", etc.
  In absence of these tools one can not have i18n and l10n changes automated in build.
  Adding "qttools-native" to "meta-qt5" Open Embedded layer provide those tools.
  Using Qt-Tools i18n and l10n changes can be automated.

recipes-qt5: Drop 5.0.2 version and 2nd qtwayland recipe

* this will make maintaining meta-qt5 a bit easier

qtbase: be more specific in opengl switch with gl in PACKAGECONFIG

* full GL is called desktop in qtbase configure
* without this it will try to autodetect and doesn't fail when
  e.g. mesa wasn't built before qtbase
