[spp] [PATCH 4/6] controller: add pcap support for pri completion

[ogawa.yasufumi@lab.ntt.co.jp]

From: Yasufumi Ogawa <ogawa.yasufumi@lab.ntt.co.jp>

This update is to add `pri; launch` completion for pcap. Optional args,
`--out-dir` and `--fsize`, are expected to be given by user and not
completed. Here is an example.

  # press TAB after `pri; launch pcap 2 `
  spp > pri; launch pcap 2 -l 1,2-3 ... -s 192.168.1.100:6666 -c phy:0
