test: use ss -lx instead of netstat by default

Browse Source 
netstat is deprecated on CentOS/RHEL in favor of
iproute utilities.  At least on one of the systems
in our test pool, netstat isn't installed - we could
install it but let's instead try to use ss if it's
available and still fall back to netstat when it's
not.

While here, remove waitforlisten_tcp instead of
changing it to use ss.  We are not using waitforlisten_tcp
anywhere and do not recommend enabling RPC over TCP except
for test purposes.
