[oe] meta-qt5 nothing provides qtdeclarative-plugins

[Paul Knopf]

When I try to use "packagegroup-qt5-qtcreator-debug", I get this error.

nothing provides qtdeclarative-plugins needed by
packagegroup-qt5-qtcreator-debug-1.0-r0.noarch

I am using poky/pyro, with meta-qt5/master
(3ae86cb32edd1449f702e0a094929ae9b21ce191).

I checked the build/workspace directory for this recipe, and indeed, no
files are being put into the qtdeclarative-plugins package. The build
directory contains no plugins directory.

I checked the morty branch and some "plugins/qmltooling/libqmldbg_*".so"
files were being placed inside of the "qtdeclarative-plugins" package.

Does the "packagegroup-qt5-qtcreator-debug" need to remove the
"qtdeclarative-plugins" dependency, or does the qtdeclarative recipe need
to be fixes to include plugins in the build output?
