selftests: drv-net: Strip '@' prefix from bpftrace map keys
The '@' prefix in bpftrace map keys is specific to bpftrace and can be
safely removed when processing results. This patch modifies the bpftrace
utility to strip the '@' from map keys before storing them in the result
dictionary, making the keys more consistent with Python conventions.

selftests: drv-net-hw: Add a test for symmetric RSS hash
Add a selftest that verifies symmetric RSS hash is working as intended.
The test runs iterations of traffic, swapping the src/dst UDP ports, and
verifies that the same RX queue is receiving the traffic in both cases.

selftests: drv-net: improve the use of ksft helpers in XSK queue test
Avoid exceptions when xsk attr is not present, and add a proper ksft
helper for "not in" condition.

selftests: drv-net: add a way to wait for a local process
We use wait_port_listen() extensively to wait for a process
we spawned to be ready. Not all processes will open listening
sockets. Add a method of explicitly waiting for a child to
be ready. Pass a FD to the spawned process and wait for it
to write a message to us. FD number is passed via KSFT_READY_FD
env variable.
Similarly use KSFT_WAIT_FD to let the child process for a sign
that we are done and child should exit. Sending a signal to
a child with shell=True can get tricky.
Make use of this method in the queues test to make it less flaky.
