When running ovsdb-server under gdb, there is a race that ovs-vsctl
command can be called before ovsdb-server is fully launched. This will
cause ovs-vsctl to fail. This patch fixes this by delay issuing
the ovs-vsctl command until ovsdb-server is fully launched.

v1->v2:
add a small delay before going to wait loop
in wait loop, use sleep 1, instead of sleep 0
