- Rename IS_KERNPROC() macro to PSKIP() and extend its functionality.
Now it'll skip calling process and system processes when -S is not given.
As a side effect it fixes '-n' option. Before it was always matching
calling process (because of missing 'if (kp->ki_pid == mypid)' check)
and after that, calling process was ignored.
- When '-l' option is given and there are no arguments, use p_comm as an
arguments list (this is helpful for kernel threads matching).
