Capture the stdout and stderr based on environment

Browse Source 
Capture the stdout and stderr based on the environment variable
OS_STDOUT_CAPTURE and OS_STDERR_CAPTURE. This is helpful for using
pdb and ipdb for debug.
This patch does not change the behavior of testr, because the
variables are set to 1 in `.testr.conf` file.
