cgroup: fix strstrip() misuse

cgroup_write_X64() and cgroup_write_string() ignore the return value of
strstrip().  it makes small inconsistent behavior.

example:
=========================
 # cd /mnt/cgroup/hoge
 # cat memory.swappiness
 60
 # echo "59 " > memory.swappiness
 # cat memory.swappiness
 59
 # echo " 58" > memory.swappiness
 bash: echo: write error: Invalid argument

This patch fixes it.
