use new method of setting locale and other environment variables

The old method left settings in the environment.  The new method takes
care of clearing them after use.  In this module, the old method was
also setting the environment too late to affect all the command line
tools which lead to a bug.

Fixes https://github.com/ansible/ansible/issues/14264
