cgroup: Replace sscanf with virStrToLong_ll
The switch from %lli to %lld in virCgroupGetValueI64 is intended, as virCgroupGetValueU64 uses base 10 too, and virCgroupSetValueI64 uses %lld to format the number to string. Parsing is stricter now and doesn't accept trailing characters after the actual value anymore.
