[LTP] fix for netns

[Veerendra <ve...@li...>]

Hi Subrata

Here is a patch to fix the error below.

/root/ltp-full-20081031/testcases/kernel/containers/netns/parentns.sh: 42: source: not found

Some shells are not having the cmd 'source' which inturn are failing the tests for netns in containers.
Like the abat job : 204849
http://abat.linux.ibm.com/abat-repo/logs/204...@in.../cont_ppc64:1/debug/test.log.1

I found few other ltp scripts are using the source cmd. Have others reported the same issue ? Just curious to know this .

The below patch would replace the 'source with .' for containers in netns.

Thanks
Veerendra C
