[LTP] [patch 01/12] CONTAINERS fixes a potential bug in library

[Sudhir K. <sk...@li...>]

This patch fixes some of the errors that I found in network namespace creation
library.

A file test on an unset vriable will give a pass, so the current test fails.
(var scrpt may not have been set before calling :))This patch fixes that error.
