Title:
  localectl updates /etc/default/locale without root privileges

Status in systemd package in Ubuntu:
  New

Bug description:
  localectl updates /etc/default/locale when it is run as non root user:
  $ localectl set-locale LANG=en_US.UTF-8

  $ ls -l /etc/default/locale 
  -rw-r--r-- 1 root root 17 Oct 26 12:46 /etc/default/locale

  $ groups
  christian adm cdrom sudo dip plugdev lpadmin sambashare

  $ ls -al `which localectl`
  -rwxr-xr-x 1 root root 21916 Oct  4 16:58 /usr/bin/localectl
