#56 cgroup_find_matching_rule_uid_gid() braces

[cJ]

I'm proxy-reporting a possible fix to one issue shown in this patch supposed to resolve it: http://sss.chaoslab.ru/git/?p=exherbo-repo.git;a=blob;f=packages/dev-libs/libcgroup/files/1bce3ab63968022e97599bbd73ec1a66aacf45bc.diff;h=c52bf85ba4870a469d9d21074b1adf6f89abf794;hb=41e76d8b71a059ee085af55a31d42837395cc6e1

cgroup_find_matching_rule_uid_gid() might appreciate to have some braces added.
