QMainWindowLayout: fix missing std::move() in QDebug stream operatorHEADdev

Coverity complains about a missing std::move(), because the
QDockAreaLayout streaming operator (like all non-QDebug-member ones)
takes the QDebug stream by value.

Add the missing move().

The const char* stream operator is a QDebug member, so takes the
stream by reference, so no std::move() needed.

It's a bit sad that it has come to this, but c'est la vie...

Amends 1cd7e01c909499b4c4c6d7dd250cc67bbb962141.
