Zhao Lei f5a95fa244 cli: Workaround for ps's argument

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.

Closes #788
