We were using Debian but Alpine more consistent. Use nested build.
Currently extract the hash in a nasty way but this can be fixed later
when we switch over hashing method.

This was missed when things were renamed.
The intention with this code was (apparently) to provide a (pseudo)unique
hostname in the case where something more specific was not provided (e.g. by
DHCP). Make this a little clearer by using '(none)' rather than 'linuxkit' as
the default, in the normal case this will be overwritten by something more
specific and if it isn't we will change it to something somewhat unique derived
from the MAC address (as before). nb: '(none)' is already used by Debian so I
think it is a safe choice as the sentinel value.
The use of both CONFIG_DEFAULT_HOSTNAME and the explicit /etc/hostname from
mkimage.sh is likely to be redundant in some cases, but neither seems to
completely cover all cases so keep both.

With redis-os and README documentation moved elsewhere,
the demo directory only contains the etcd demo setup.
Rename it.
