[OE-core] [PATCH V2] base-files: provide a mechanism to skip creation of the hostname file

[Mark Asselstine]

The existence of a /etc/hostname file causes any hostname provided on
the kernel command line or via dhcp to be overwritten by the
initscripts 'init.d/hostname.sh'. This change allows you to set a
value of 'none' for 'hostname' which will skip the creation of the
/etc/hostname file by the base-files package.

V2: Koen Kooi didn't want to see the handling of the hostname variable
    changed so I removed those changes and just focused on the creation
    of the /etc/hostname file.

  Changes from V1:
  * patch renamed, was 
    "base-files: allow for more flexibility related to hostname",
  * removed the rename of hostname to MACHINE_HOSTNAME
  * removed the addition made to meta/conf/local.conf.sample
