[LTP] [PATCH V3 15/23] Add periodic output for long time test.

[Tudor Florea <tudor.florea@enea.com>]

Hi
This patch was needed to avoid the timeout of the script used to parse
the redirected output of the test. That being said don't have any strong
arguments (pro or cons) of cleaning up or improving the patch.
To be pedantic, I think that a newline for every 10 minutes is a little
too seldom; maybe just adding a new line every 5 minute is acceptable.
I hope that helps,
  Tudor.
