summary: Ensure that the locale-control interface works.
details: |
The locale-control interface allows a snap to access the locale
configuration.
A snap which defines the locale-control plug must be shown in the interfaces
list. The plug must not be auto-connected on install and, as usual, must be
able to be reconnected.
A snap declaring a plug on this interface must be able to access the
/etc/default/locale file both for reading and writing. This path doesn't
exist on the excluded distributions.
