remove temporary folder on target, wait for sphinx service stop

make index can now replace /etc/sphinxsearch/sphinx.conf, post-restore-code hook removes /tmp/sphinxsearch directory on target, while loop is waiting 20s before searchservice stop is forced

c2c has fixed the permission issue on /etc/sphinxsearch/sphinx.conf. 
The file can now be replaced with sphinxsearch. So i have added this copy to the make index.
