[spp] [PATCH 1/8] shared: add func for getting dirname of secondary

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

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

To inspect the name of directory of secondary from process name, add
function `get_sec_dir()`. It is used to find the path of exec file of
secondary process.
