It's possible that someone might want to override a property for a non-syscall rule source. To assist in this, decode any source property for rules with append/override and save it in the rule_update_info object. For the source property only, the value for source can be empty e.g. 'source: ' or an empty string e.g. 'source: ""'. Both of those are considered valid but result in an empty source. A later change will ensure that the sources match up when appending/redefining/overriding/enabling. Signed-off-by: Mark Stemm <mark.stemm@gmail.com>
