[PATCH 2/2] iotests: Set LC_ALL=C for sort

[Max Reitz]

Otherwise the result is basically unpredictable.

(Note that the precise environment variable to control sorting order is
LC_COLLATE, but LC_ALL overrides LC_COLLATE, and we do not want the
sorting order to be messed up if LC_ALL is set in the environment.)
