This update for libyui fixes the following issues:

libyui was updated to 4.7.6:

Allow building with CMake 4.0

  * Bump cmake_minumum_required to 3.10, which matches what most
    other modules in libyui use (3.5 is the minimum required to be
    supportable by CMake 4.0).
  * Remove CMP0046, as CMake 4.0 no longer supports it. The OLD
    mode in any case was a workaround for 'badly written
    CMakeLists.txt', as it just instructed cmake to ignore
    non-existing dependenices listed in add_dependencies. This
    package does not rely on non-existing dependencies and builds
    perfectly without this policy.

- Do not build the qt packages (libyui-qt, libyui-qt-graph,
  libyui-qt-pkg and libyui-qt-rest-api) in SLE16 since Qt5 won't
  be available there.
- Integrated the graphviz API fix upstream (Let CMake detect graphviz version)
- graphviz API broke in a recent version update (bezier size is now
  of type size_t instead of int).
