Subject: [PATCH] init.rc: Remove cpu weight set on the root cgroup

It isn't allowed to change the cpu.share value for the root cgroup.
See kernel commit:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ec7dc8ac73e4a56ed03b673f026f08c0d547f597

This fixes the following error seen in dmesg:
init: write_file: Unable to write to '/dev/cpuctl/cpu.shares': Invalid argument

BUG: 28735908
