perf: Add a script to show packets processing

Add a perf script which shows packets processing and processed
time. It helps us to investigate networking or network devices.

If you want to use it, install perf and record perf.data like
following.

If you set script, perf gathers records until it ends.
If not, you must Ctrl-C to stop recording.

And if you want a report from record,

If you use some options, you can limit the output.
Option is below.

tx: show only tx packets processing
rx: show only rx packets processing
dev=: show processing on this device
debug: work with debug mode. It shows buffer status.

For example, if you want to show received packets processing
associated with eth4,

106133.171439sec cpu=0
irq_entry(+0.000msec irq=24:eth4)
|
softirq_entry(+0.006msec)
|
|---netif_receive_skb(+0.010msec skb=f2d15900 len=100)
| |
| skb_copy_datagram_iovec(+0.039msec 10291::10291)
|
napi_poll_exit(+0.022msec eth4)

This perf script helps us to analyze the processing time of a
transmit/receive sequence.
