dev-qt/qtdeclarative: guard against incomplete installs (qt6)

The guard can be tested by doing:
  emerge -C qtshadertools:6
  emerge -O qtdeclarative:6
Then qtdeclarative will ignore the missing dep and try to install
without QtQuickControls2 (for one), and guard should stop it.

Bit wasteful, but revbump to ensure everyone has a working copy.
fwiw skipping 6.7.2 given afaik issue only happen on upgrades
and 6.7.2 is old and kind of a well established install by now.
