diffconfig: Gracefully exit if the default config files are not present
Handle gracefully the instance where config files are not present. Compatible with python versions 2.5, 2.6 and 2.7. The try/except is forward compatible with python version 3 once the entire script is ported. Signed-off-by: Mike Pagano <mpagano@gentoo.org> Signed-off-by: Michal Marek <mmarek@suse.cz>
