Bug description:
  [Impact]

  accountsservice includes a function for checking the validity of
  locales, and it incorrectly considers "C.UTF-8" to be invalid. It
  leads to incorrect behavior under certain conditions and also a crash
  if the function was triggered from language-selector-gnome.

  Even if this only makes a difference in special corner cases, it
  happens often enough to justify this SRU:

  https://errors.ubuntu.com/?release=Ubuntu%2020.04&package=language-
  selector&period=year

  (It's the top ranked crash type in the list.)

  The version in focal-proposed fixes the issue.

  [Test case]

  Make a fresh install of Ubuntu 20.04 (a VM works fine)

  Once logged in:

  * Install accountsservice, gir1.2-accountsservice-1.0 and
    libaccountsservice0 from focal-proposed

  * Open /etc/default/locale for editing, replace its contents with
    the single line:

    LANG=C.UTF-8

    and reboot.

  Open Language Support and change language (drag any language above
  the "English" item)

  Open ~/.pam_environment and find that e.g. LANG is now the locale
  representing the language you selected, while e.g. LC_TIME is set to
  "C.UTF-8".

  [Regression risk]

  This is a oneliner which white list "C.UTF-8" as a valid locale name.
  I can't think of a case where this would cause unexpected behavior.
