apply socket activation to amd and amd_session_agentsubmit/tizen_wearable/20150225.030214submit/tizen_tv/20150225.030125submit/tizen_mobile/20150225.030152accepted/tizen/wearable/20150225.053943accepted/tizen/tv/20150225.100213accepted/tizen/mobile/20150225.053512

- add socket unit and install unit file by making link in .target.wants
folder.
- Before create server socket in daemon, check if there is socket stream.
- amd and amd_session_agent can receive its preinitailized sockets from
systemd.
