kernel: Deactivate CONFIG_BINFMT_MISC

CONFIG_BINFMT_MISC allows it to add support for new executable formats to the kernel from user space, the kernel will then detect for example a java binary and call the java execution program automatically. I am not aware that this feature is used in OpenWrt and this could be used to exploit something. Deactivate it for all targets for now. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
