Restore the persistent server option in the LB tests

The cb85dcdf5e2cf53ac21bb97382e03a8c5b47042f putted the
nc command into loop in order to tolerate busybox/nc versions
without persistent server option (cirros 0.3.3).

Unfortunately the above change also changed -ll option to -l.
The nc with -ll option provides 'never stop listening' service,
without this behavior the test can fail frequently/always
in several setup.

This change restores the -ll option, which does not causes issues
when you use  cirros 0.3.3 image, and gives stability with cirros 0.3.2
 + haproxy 1.5.x.

Note: The gate is using 0.3.2 cirros and HaProxy 1.4.x,
On the gate this change effectively restores the behavior before
cb85dcdf5e2cf53ac21bb97382e03a8c5b47042f.
