selftests: net: more strict check in net_helper

The helper waiting for a listener port can match any socket whose
hexadecimal representation of source or destination addresses
matches that of the given port.

Additionally, any socket state is accepted.

All the above can let the helper return successfully before the
relevant listener is actually ready, with unexpected results.

So far I could not find any related failure in the netdev CI, but
the next patch is going to make the critical event more easily
reproducible.

Address the issue matching the port hex only vs the relevant socket
field and additionally checking the socket state for TCP sockets.

selftests: net: Remove executable bits from library scripts

setup_loopback.sh and net_helper.sh are meant to be sourced from other
scripts, not executed directly. Therefore, remove the executable bits from
those files' permissions.

This change is similar to commit 49078c1b80b6 ("selftests: forwarding:
Remove executable bits from lib.sh")

Fixes: 7d1575014a63 ("selftests/net: GRO coalesce test")

selftests/net: synchronize udpgro tests' tx and rx connection

The sockets used by udpgso_bench_tx aren't always ready when
udpgso_bench_tx transmits packets. This issue is more prevalent in -rt
kernels, but can occur in both. Replace the hacky sleep calls with a
function that checks whether the ports in the namespace are ready for
use.
