update-rc.d: process symlinks recursively
When processing startup scripts which use update-alternatives, we need to keep
resolving the symlink recursively until we hit a real file, due to the
alternatives indirection. This fixes the ability to run certain postinsts at
do_rootfs time, which is needed for good read-only-rootfs support.
