[fsresizer] [partition] Gracefully fail on missing dependencies

- If KPMcore is found -- it requires some other KDE Frameworks but
   at least in pre-4.0 versions doesn't check very well for them --
   then missing its dependencies is no cause for CMake failure.
   Instead, log it nicely and suppress the module.
