[PATCH v4 2/5] random: conditionally compile code depending on LRNG

When selecting the LRNG for compilation, disable the legacy /dev/random implementation. The LRNG is a drop-in replacement for the legacy /dev/random which implements the same in-kernel and user space API. Only the hooks of /dev/random into other parts of the kernel need to be disabled.
