dm-verity: ensure people don't ignore the DISTRO_FEATURES warning

Some platform creators tend to list a whole bunch of layers by
default in conf/bblayers.conf.  Without getting into the debate of
whether that is a good idea, it can tend to have the effect of
people seeing the meta-security DISTRO_FEATURES warning time and
time again and becoming essentially numb to it.

After having fallen into this trap myself, I figured it was worth
the extra mention in the dm-verity doc so there is a better chance
of users realizing "hey - this applies to me!".

Kernel configuration for dm-verity happens automatically via IMAGE_CLASSES
which will source features/device-mapper/dm-verity.scc when dm-verity-img
is used. [See commit d9feafe991c]
IMPORTANT: As per the top level README, you *must* put security in the
DISTRO_FEATURES, or else you won't get the dm-verity kernel settings.
