modules: patch meson subprojects to use local dependencies

Usually we want no difference between the upstream project that we fork
via git-subtree, and our copy. However, for the subprojects, we need to
patch them. Do it.

If you know a better way, that allows to overwriting the subprojects
please send a patch.
