[packaging] Add telepathy-qt5.patch for now to telepathy-qt4.spec as a source.

This fixes warning that is caused in boss review. Other option would be to disable that check,
however disabling the check can cause errors in the future, so as we know what we are doing
adding the patch to sources should be just fine.
