This enables the support for the rootless container mode. There are many
restrictions on what rootless containers can do, so many different runC
commands have been disabled:
* runc checkpoint
* runc events
* runc pause
* runc ps
* runc restore
* runc resume
* runc update
The following commands work:
* runc create
* runc delete
* runc exec
* runc kill
* runc list
* runc run
* runc spec
* runc state
In addition, any specification options that imply joining cgroups have
also been disabled. This is due to support for unprivileged subtree
management not being available from Linux upstream.

the `-p pidlist` flag of `ps` command selects the process whose process
ID numbers apper in `pidlist`.[1]
This patch use `-p pidlist` to filter process which we want.

Currently, ps command can not support argument:
(But following usage is in manual)
| # ./runc ps 123 -ef
| Incorrect Usage.
|
| NAME:
| runc ps - ps displays the processes running inside a container
|
| USAGE:
| runc ps [command options] <container-id> [ps options]
|
| OPTIONS:
| --format value, -f value select one of: table or json
|
| flag provided but not defined: -ef
| #
Instead of using odd command like:
| # ./runc ps -- 123 -ef
We can make it seems little better:
| # ./runc ps 123 -- -ef
| UID PID PPID C STIME TTY TIME CMD
| root 29046 29038 0 11:18 pts/2 00:00:00 sh
| #
This patch also fixed manual which can not working in current
code.

Argument of "ps options" for ps command is a optional parameter.
Should use [] instead of <> in manual.

This patch add manual for ps command, and remove remove example
for --format command, which is not necessary.
