core/namespace: fix path sorting
The comparison function we use for qsorting paths is overly indifferent. Consider these 3 paths for sorting: /foo /bar /foo/foo qsort() may compare: "/foo" with "/bar" => 0, indifference "/bar" with "/foo/foo" => 0, indifference and assume transitively that "/foo" and "/foo/foo" are also indifferent. But this is wrong, we want "/foo" sorted before "/foo/foo". The comparison function must be transitive. Use path_compare(), which behaves properly. Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1184016
