[dts] [PATCH]tests multiprocess: fix commands send to wrong session

[Tu, LijuanX A]

Hi ,huilong
	This bug  happened by  using kill_all .
In the case ,we using alt_session run simple_mp primary , 
kill_all send shell-cmd "kill" also using alt_session,
so the "kill" was send to dpdk app " simple_mp " .

some related log like this:

ERROR: lsof -Fp /var/run/.rte_config
Command not found
simple_mp >
---snip---
buffer (last 100 chars): '-Fp /var/run/.rte_config\r\r\nCommand not found\r\n\r\nsimple_mp > exit\r\r\nCommand not found\r\n\r\nsimple_mp > '

Hi lijuan,
Could you used kill_all function for kill dpdk app process, It in crb.py, you can check this function.
