cgroup: Fix 64-bit division in cgroup.stat.local
Fix the following build error for 32-bit systems:

>> kernel/cgroup/cgroup.c:3781:(.text+0x28f4): undefined reference to `__aeabi_uldivmod'
arm-linux-gnueabi-ld: (__aeabi_uldivmod): Unknown destination type (ARM/Thumb) in kernel/cgroup/cgroup.o
>> kernel/cgroup/cgroup.c:3781:(.text+0x28f4): dangerous relocation: unsupported relocation
