kernel: Deactivate CONFIG_BINFMT_MISC

Browse Source 
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.
