[spp] [PATCH 6/8] tools/sppc: add workdir docker option

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

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

Some of apps require to be launched from specific directory even if PATH
is configured properly. For instance, pktgen should be launched from
project root because for finding `Pktgen.lua` in the directory.

This update is for adding workdir option for specifying a directory
from which the app is launched.
