instead of assigning plugins to the first module which claims the whole
type, try to assign it to a module which the plugin claims to extend.
as we are getting stricter in that go, somebody needs to claim the
'generic', 'platformthemes', and 'platforminputcontexts' plugin types.
the natural claimant is QtGui. however, as we don't want to auto-link
any of these plugins, make them all claim that they extend a
non-existing module.
QtGui also claims 'iconengines' plugins.
the 'printsupport' plugins are also claimed by the respective module.
