Alessandro Carminati (Red Hat) 1d01d0f498 selftests/bpf: Prevent client connect before server bind in test_tc_tunnel.sh
[ Upstream commit f803bcf9208a2540acb4c32bdc3616673169f490 ]

In some systems, the netcat server can incur in delay to start listening.
When this happens, the test can randomly fail in various points.
This is an example error message:

   # ip gre none gso
   # encap 192.168.1.1 to 192.168.1.2, type gre, mac none len 2000
   # test basic connectivity
   # Ncat: Connection refused.

The issue stems from a race condition between the netcat client and server.
The test author had addressed this problem by implementing a sleep, which
I have removed in this patch.
This patch introduces a function capable of sleeping for up to two seconds.
However, it can terminate the waiting period early if the port is reported
to be listening.
