Expand the existing netconsole selftest to verify the functionality of
the recently added CPU number auto-population feature in the netconsole
userdata.
The changes include enabling the "populate_cpu_nr" option on the
netconsole target before sending the test data, and validating that the
received data on the listener side contains a "cpu=" entry in the
userdata, indicating that the CPU number was successfully
auto-populated.
This addition to the netconsole selftest ensures that the new CPU number
auto-population feature works as expected and helps catch any
regressions in this functionality.
