Upgrade the overlayfs branch to Linux 4.x
It’s now in sid. The main blocker is that the amd64 kernel flavour is
not built anymore for the i386 architecture, so we have to use dpkg --add-architecture amd64, and adjust APT sources so that we fetch the
indices (of the suites we want to fetch the kernel from) for amd64 in
addition to i386.
