[poky] [PATCH] base-files: Let user set hostname

[J. Tang]

By default, poky always sets the hostname to machine type. This adds
the environment variable $MACHINE_HOSTNAME that holds the intended
hostname. If set, it overrides any default hostnames. The user can set
$MACHINE_HOSTNAME within his/her local.conf.
