base-files: fix ramoverlay function with kernels 3.18+
Even though there are not many users left within the OpenWrt tree it seems this function broke during the kernel 3.18 transition. Fix it by providing a workdir as required by overlayfs. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> SVN-Revision: 47015
