selftests: drv-net: rss_input_xfrm: Check test prerequisites before running

Browse source 
Ensure the following prerequisites before executing the test:
1. 'socat' is installed on the remote host.
2. Python version supports socket.SO_INCOMING_CPU (available since v3.11).

Skip the test if either prerequisite is not met.
