[spp] [PATCH 15/15] tools/sppc: add spp launcher script

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

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

SPP consists of a primary and several secondary processes. It usually
five or more processes are required to configure network, but it takes
a time to launch processes one by one.

This patch is for adding a helper script to launch all of processes
at once.
