Ignore the "region" gsettings value

Steps to show an example when this issue matters:

* English install from a US location
* Change formats from g-c-c to en_DK.UTF-8
  - to get reasonable date formats
  - this changes both "region" and ~/.pam_environment
* Install French from Language Support
* Change formats from Language Support to fr_FR.UTF-8
  - this changes ~/.pam_environment but not "region"
* Relogin

Result:

$ cat .pam_environment
LC_NUMERIC=fr_FR.UTF-8
LC_TIME=fr_FR.UTF-8
LC_MONETARY=fr_FR.UTF-8
LC_PAPER=fr_FR.UTF-8

      variables saved in ~/.pam_environment (LP: #1722002).
  * debian/control, debian/control.in:
    - Suggest gnome-user-docs instead of gnome-user-guide
      (LP: #1691867).
