ignore travis code sniff check in template files

In pull #133 was removed this line https://github.com/joomla-projects/com_localise/pull/133/files#diff-2537849347c1077284ce7fc88878e4c5R6 witch was good.

But we still need to ask travis to ignore the /tmpl/ files when doing the PHPCS because we use inline PHP in templates instead of normal PHP.

After this pull travis should not be checking this https://travis-ci.org/joomla-projects/com_localise/jobs/28164657#L553
