The cpuset file is a legacy attribute that is bound primarily to cpuset

Followup to commit b0ced9d378d49 ("cgroup/cpuset: move v1 interfaces to
cpuset-v1.c") and hide CONFIG_PROC_PID_CPUSET under CONFIG_CPUSETS_V1.
Drop an obsolete comment too.

I do have some reservation in taking out /proc/<pid>/cpuset by default
as CPUSETS_V1 is off by default. This may break some existing user scripts.
Also the statement that the cpuset file is the same as the path in
cgroup file in unified hierarchy is not true if that cgroup doesn't have
cpuset enabled.
