kata_proxy: Set Setsid to true when exec kata-proxy

Browse Source 
There is an issue that ctrl-c stop vmcache server will stop all
containers that its VM is created by it.
The cause is kata-proxy and vmcache server use same tty, for example:
ps -e | grep kata
3617 pts/5    00:00:00 kata-runtime
3636 pts/5    00:00:00 kata-proxy
Ctrl-c will send signal to both kata-proxy and vmcache server.
Then the containers that its VM is created by this vmcache server will
quit with it.

Set Setsid to true when exec kata-proxy to handle this issue.

Fixes: #1726
