PROXY: proxy_child should work in non-root mode
According to design page[1], proxy_child should run
with root privileges in non-root mode however proxy_child
did not have setuid bit.
After setting setuid bit proxy_child will be executed with extra privileges.
The effective user ID will be 0 but effective group ID will be still
the same as egid of sssd_be. Therefore gid of private pipe for
proxy_child should be the same. Otherwise proxy_child will fail
due to wrong permissions of unix pipe (sbus_client_init -> check_file)
