Fix set_hostname

Description of problem:

Distro.set_hostname() uses wrong hostname when calling _apply_hostname().

On initial boot, the hostname is set to the short name, but after reboot it is set to the fqdn. 

Version-Release number of selected component (if applicable):

  0.7.4-2

How reproducible:

  On openstack or AWS, use the following user data:

    #cloud-config
    manage_etc_hosts: true
    hostname: myhostname
    fqdn: myhostname.domain.tld

  Launch the machine and login. Then run hostname:

    [root@myhostname ~]# hostname
    myhostname

  Reboot.

  Login and run hostname again:

  [root@myhostname ~]# hostname
  myhostname.domain.tld


Expected results:

  [root@myhostname ~]# hostname
  myhostname.domain.tld
