This command looks through the currently running processes and kills
the those that match the selection criteria. This way system can send
signal to processes by name and without knowing the IDs.
Example (kill application hello):
pkill -15 hello
The command can be turned off by NSH_DISABLE_PKILL option and depends
on FS_PROCFS.

Currently new users when try to run NuttX using the SIM
get stuck into simulator, because they have no idea that
poweroff command is used to leave it. Let use KISS approach
and use quit as an alias to poweroff command.

From comment in cmd_ifconfig, it seems that we support `ifconfig [interface]`, but actually not considering the interface param now. After this commit, we only print the information of interface specified in param, just like linux.
