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.
