Add GRND_INSECURE from Linux 5.6 to sys/random.h
This patch adds the GRND_INSECURE constant from Linux 5.6 to glibc's sys/random.h. This is also added to the documentation. The constant acts as a no-op for the Hurd implementation (as that doesn't check whether the flags are known), which is semantically fine, while older Linux kernels reject unknown flags with an EINVAL error. Tested for x86_64.
