UBUNTU: [Config] packaging: adjust perms on vmlinuz as well

Since kernel symbols are resolvable internally to the kernel, the kernel
itself has a map of the symbols. Continuing the tradition of frustrating
off-the-shelf kernel exploits, make vmlinuz unreadable for non-root, just
like has been done for System.map, etc.
