This commit adds a patch for QWindowKit to ensure that it always
installs its dependency QMSetup in a directory where CMake will be able
to find it. This makes the previous QWindowKit patch unnecessary and
fixes a build issue when packaging Jami on Debian and Ubuntu that
started occurring when QWindowKit was updated in commit 6b70ffc.
