Allow disabling wayland integration for Qt6 builds

Upstream has removed the required toggle for wayland integration, and instead
is forcing it when the program is being built with Qt6 version 6.5.0 or higher.

Currently this is simple to work around, but its future feasibility remains to
be seen, depending on what upstream thinks about this.
